In 2016, record new renewable energy added, and cheaply

April 12, 2017 by Climate portal editor Leave a Comment

Recent reports bring positive news related to renewable energy investment and the feasibility of a 100% renewable energy future. The UN Environment Programme (UN Environment, or UNEP), the Frankfurt School-UNEP Collaborating Centre, and Bloomberg New Energy Finance released a report titled ‘Global Trends in Renewable Energy Investment 2017,’ which finds that wind, solar, biomass and waste-to-energy, geothermal, small hydro and marine sources added 138.5 gigawatts to global power capacity in 2016, up 8% from the 127.5 gigawatts added in 2015.

The report indicates that as the cost of clean technology continues to fall, the world added record levels of renewable energy capacity in 2016, at an investment level 23% lower than the previous year. According to UN Environment, the added generating capacity roughly equals that of the world’s 16 largest existing power producing facilities combined.

Global Trends in Renewable Energy Investment 2017, published on April 6th by UN Environment, the Frankfurt School-UNEP Collaborating Centre, and Bloomberg New Energy Finance, finds that all investments in renewables totaled $241.6 billion (excluding large hydro). These investments added 138.5 gigawatts to global power capacity in 2016, up 9 per cent from the 127.5 gigawatts added the year before.

Investment in renewables capacity was roughly double that in fossil fuel generation; the corresponding new capacity from renewables was equivalent to 55 per cent of all new power, the highest to date. The proportion of electricity coming from renewables excluding large hydro rose from 10.3 per cent to 11.3 per cent. This prevented the emission of an estimated 1.7 gigatons of carbon dioxide.

The total investment was $241.6 billion (excluding large hydro), the lowest since 2013. This was in large part a result of falling costs: the average dollar capital expenditure per megawatt for solar photovoltaics and wind dropped by over 10 per cent.

India pushes solar target up to 100 GW

June 18, 2015 by Climate portal editor Leave a Comment

ICP_MNRE_solar

The Union Cabinet has decided that India’s solar power capacity target under the National Solar Mission is to be dramatically revised upwards to reach 100,000 MW (or 100 GW) by 2022. The new solar target of 100 GW is expected to abate over 170 million tonnes of CO2 over its life cycle.

In the first phase, the Government of India is to provide capital subsidy to promote solar capacity addition in the country. This capital subsidy will be provided for rooftop solar projects in various cities and towns for projects to be developed through the Solar Energy Corporation of India (SECI) and for decentralized generation through small solar projects.

MNRE_solar2Solar power projects are also to be developed using what the government calls a “bundling mechanism” together with thermal power with investments envisaged to come from large public sector undertakings and also from independent power producers. State governments meanwhile have also come out with state-specific solar policies to promote solar capacity addition.

The statement by the Ministry of New and Renewable Energy (MNRE) has said: “Solar power can contribute to the long term energy security of India, and reduce dependence on fossil fuels that puts a strain on foreign reserves and the ecology as well.” The solar manufacturing sector in India will benefit with this long term trajectory of solar capacity addition.

This scaling up plan for solar power has a target of 40 GW through decentralised solar power generation in the form of grid connected rooftop projects. Coordination is required, says the central government, so that the land areas required for the largest solar farms are unculturable land, for solar photo-voltaic units to be encouraged, and for large government buildings to be identified for rooftop solar projects, for the Ministry of Urban Development to make mandatory the provision of roof-top solar and 10% generation of renewable energy (presumably per building unit).

Financial incentives envisaged include giving the status of ‘infrastructure’ for solar projects, raising tax-free solar bonds, including roof-top solar units within housing loans provided by scheduled banks. It is also foreseen that amendments to the Electricity Act will be needed so that renewable purchase obligations and renewable generation obligations can be enforced.

The National Solar Mission was begun in 2009 with an initial target for grid-connected solar projects of 20,000 MW by 2022. In the last two to three years, the sector has witnessed rapid development with installed solar capacity increasing from 18 MW to about 3,800 MW during 2010-15. The price of solar energy has come down significantly from Rs 17.90 per unit in 2010 to under Rs 7 per unit today.

Climate measures that matter

October 8, 2014 by Climate portal editor Leave a Comment

RG_ICP_countries_emissions_201410

India has been saying during the last several international negotiations about climate change that our country, like other ‘developing’ countries, has a right to development. What this means is India has officially said our country will continue to burn coal and petroleum products in quantities that contribute to India emitting 1.954 million tons of CO2 a year (this figure is for 2012).

The ‘developed’ world (mostly countries in western Europe and North America) point to this large quantity and demand that India (and China, which emits very much more) do something to halt this rise and to decrease it. India’s response has been – recognise what you have done from the time of the Industrial Revolution and then we’ll resume talking.

This is unlikely to result in any constructive recognition of all that is linked. A country’s total emissions is one part of the ‘development’ picture and others are at least as important. There are also tons of CO2 emitted per capita (India has often said that its per capita emissions are far below those of the West). And there is per capita consumption of electricity (which is still mainly generated by burning coal).

That is why, when we look at the relationship between these three measures for a country, and between countries for any one of these three measures, we see connections that are otherwise missed due to a focus on a single measure. Our diagram, ‘Climate Measures that Matter’, helps explain these connections. It can be used as an aide to understanding better India’s position at climate negotiations, and provides much-needed context to the arguments about a country’s total emissions and its per capita emissions. [See the statement by Minster for Environment Prakash Javadekar, at the United Nations Climate Summit 2014.]

This diagram is an aide to understanding better India’s position at climate negotiations. It provides much-needed context to the arguments about a country’s total emissions and its per capita emissions.

The country and energy data used in this diagram is for the latest year which is 2012. The source for the data is the International Energy Agency’s ‘Key World Energy Statistics 2014’ . This selection of countries compares countries of South Asia, East Asia, the larger economies of the OECD, the BRICS, other European countries, and countries of the Middle East. For each of the three measures, the size of the circles are relative to each other.

One could argue that the relationship between three measures for any country shows its responsibilities towards curbing the use of fossil fuels both nationally and individually, and towards capping electricity use. For example, per capita electricity use in a number of the countries shown in the diagram is seven or eight times more, and even ten times more and above, than India’s use.

Our South Asian neighbours – Bangladesh, Nepal, Pakistan and Sri Lanka – have by all three measures relatively small global impacts. The size of our population and the depth of our industry and economy however has made India the third largest emitter of CO2 (after China and the USA). But if India seeks some sort of ‘parity’ in electricity use – or if India sees the low per capita CO2 emissions as a ‘development’ gap – our total contribution to CO2 emissions will only rise faster, hurting the environment that we share with our neighbours.

The diagram helps display some of the most glaring and conspicuous differences between countries’ impacts on the atmosphere and ecosphere. These differences can be taken to mean fuel use and consumption must be halted and stringently curbed, whether or not the Kyoto Protocol and a successor treaty exist. That would be the way of acting responsibly for a country. [See the text of the Joint Statement issued at the 18th BASIC Ministerial Meeting on Climate Change in August 2014.]

These differences can also mean that the ‘developed’ countries recognise – as we and many ‘developing’ and ‘less developed’ countries have been reminding them repeatedly – that the way their economies and societies have functioned has caused much of the problem in the first place, and they must stop shunting the onus of responsibility onto us.

Finally, these differences should also show why being small is not being ‘poor’ and ‘less developed’. Households and families that use few kilowatts instead of many, burn few litres of fuel instead of many, are very much more responsible and environmentally balanced than others. It is the small circles in this diagram that ought to be the inspiration.

India’s giant megawatt trap

September 10, 2014 by Climate portal editor 1 Comment

Electricity as fundamental right and energy convenience as the basis of ‘development’ in Bharat and in India. If this is what Piyush Goyal means when he says his government is “is committed to ensure affordable 24×7 power” then it will come as yet another commitment that supports energy provision and consumption as the basis for determining the well-being of Bharat-vaasis and Indians (the UPA’s Bharat Nirman was the predecessor). But the Minister of State (Independent Charge) for Power, Coal and New and Renewable Energy cannot, using such a promise, ignore the very serious questions about the kind of ‘development’ being pursued by the NDA-BJP government and its environmental and social ramifications.

Goyal has said, via press conferences and meetings with the media, that the NDA government is committed to ensuring affordable power at all times (’24 x 7′ is the expression he used, which must be banished from use as being a violent idea – like nature our lives follow cycles of work and rest and ’24 x 7′ violently destroys that cycle). Goyal has promised, pending the taking of a series of steps his ministry has outlined, that such a round the clock provision of electric power will be extended to “all homes, industrial and commercial establishments” and that there will be “adequate power for farms within five years”.

Some of the very serious questions we raise immediately pertain to what Goyal – with the help of senior ministry officials and advisers – has said. The NDA-BJP government will spend Rs 75,600 crore to (1) supply electricity through separate feeders for agricultural and rural domestic consumption, said Goyal, which will be used to provide round the clock power to rural households; and (2) on an “integrated power development initiative” which involves strengthening sub-transmission and distribution systems in urban areas. This is part of the “transformative change” the ministry has assured us is for the better. Goyal and his officials see as a sign of positive transformation that coal-based electricity generation from June to August 2014 grew by nearly 21 per cent (compared with the same months in 2013), that coal production is 9% higher in August 2014 compared with August 2013, and that Coal India (the largest coal producer company in the world which digs out 8 of every 10 tons of coal mined in India) is going to buy 250 more goods rakes (they will cost Rs 5,000 crore) so that more coal can be moved to our coal-burning power plants.

UN_Climate_Summit_2014_smWe must question the profligacy that the Goyal team is advancing in the name of round the clock, reliable and affordable electricity to all. To do so is akin to electoral promises that are populist in nature – and which appeal to the desire in rural and urban residents alike for better living conditions – and which are entirely blind to the environmental, health, financial and behavioural aspects attached to going ahead with such actions. In less than a fortnight, prime minister Narendra Modi (accompanied by a few others) will attend the United Nations Climate Summit 2014. Whether or not this summit, like many before it, forces governments to stop talking and instead act at home on tackling anthropogenic climate change is not the point. What is of concern to us is what India’s representatives will say about their commitment to reduce the cumulative impact of India’s ‘development’, with climate change being a part of that commitment.

At the UN Climate Summit 2014, it will be heard (in as many languages as there are translators available for them) that energy demand is growing along with expanding global wealth (but the UN will not say how unequally that extra wealth has been distributed). There will be grave references made to growing populations with a large number still without the round the clock electricity that Goyal has promised. Many speakers (eminent experts, as the UN system calls them) will be mobilised to remind the gathering that a shift toward renewable sources of energy (such as solar, wind and geothermal) is needed, that greater energy efficiency in appliances, buildings, lighting and vehicles are needed, and that this is so because it is essential to use the world’s resources sustainably, to diversify economies and successfully address the challenge of climate changes. It will sound suitably solemn and uplifting at the UN headquarters in New York, but the story at home in Bharat and India is solemn and deeply worrisome.

Some of the tale is of very short-term inconvenience, such as when Mumbai went without electricity for a few hours on 02 September. The business and financial media reported that “back-up generators at banks and brokerages ensured that financial business was largely unaffected” and then circulated the familiar complain that India does not generate enough electricity to meet rapidly rising demand, that a severe shortage of coal (half our 150-odd coal burning plants are reported as having no more than a week’s supply of coal) has raised fears of more widespread blackouts.

Dire tweets from a leading industrialist, Anand Mahindra, were also reported: “Dark office in Mumbai. Lights out in the whole area. The coal crisis is beginning to literally show its dark side. A threat to the India story.” This senior member of the clutch of companies on the Bombay Stock Exchange ‘A’ List underlining a threat to the ‘India story’ led the business and financial media to quickly exert psychological duress on the NDA-BJP – “any grid collapse would cast doubt on the crisis management skills of the new government led by Prime Minister Narendra Modi”.

Electricity as fundamental right and energy convenience is moreover essential in the view of Indian industry to reaching the 8% per year GDP growth threshold, which this section appears to consider the single goal of the Republic of India. Hence where energy and the generation and provision of electricity is concerned, Goyal and his team have listed eight steps their ministry will undertake: (1) to rationalise coal supplies (by which is meant, as far as I can make out, move coal fewer kilometres to nearer power plants instead of distant ones); (2) create a statutory coal regulator; (3) civil nuclear cooperation agreement (Australia mentioned for uranium); (4) surveillance at major coal mines to control coal theft; (5) hydro-electric power generation in Jammu and Kashmir (“fast track” they say); (6) environmental clearances (“government will speed up environment and forest clearances to projects”); (7) bring more generation capacity at gas-based power online; (8) clear the solar ultra mega power plant at Sambhar near Jaipur, Rajasthan (the area is a site for migratory birds and an ecological refuge).

Had we an environment regulatory system and a project appraisal and clearances mechanism that protected environment, biodiversity, natural resources and our natural heritage, points 3, 5, 6 and 8 could under no circumstance have appeared on the Ministry of Power list. But the NDA-BJP government has in its first three months taken swift steps to eases clearances for industrial and infrastructure projects. Goyal’s colleague in the cabinet, Prakash Javadekar (minister of state for environment, forests and climate change), has worked to get the MoEF&CC to loosen the norms for expansion of coal mining projects producing up to 8 million tonnes of coal a year, and to adopt a ‘cluster approach’ in clearing smaller mines in the coal-rich belts of India. The environment ministry is also – as the Rajya Sabha was told – “streamlining environmental clearance process by delegating more powers to the State level Environment Impact Assessment Authorities (SEIAAs) for granting” such clearances, and neither house of Parliament has inquired critically as to whether the states so favoured have in place the evaluating expertise and capacities of sufficient authority and independence to not clear those projects which will harm environment, biodiversity, natural resources and our natural heritage.

Poor ambient air quality in our cities is hazardous to health, and emissions from coal-burning power plants are an important contributor to urban air pollution. This chart of a New Delhi region is courtesy Asia Air Pollution Real-time Air Quality Index (AQI).

While industry and a growing urban middle class expect ‘development’ and convenience, represented mainly by uninterruptible kilowatts, and exert a disproportionate amount of pressure on the state to fulfil these desires, there is a short list of steps very different from Goyal’s which must be recognised by the NDA-BJP government and state governments. This is:

(1) There is 172,986 MW of thermal power capacity (149,178 coal, 22,608 gas and 1,200 diesel), 40,798 MW of hydro-electric, 31,692 MW of renewables and 4,780 MW of nuclear, for a total of 250,257 MW. That’s on paper, whereas the actual power generation every average day (in 2014, according to the Central Electricity Authority, which is the apex power sector planning body) has been around 135,000 MW. From every power plant to every grid and to every distribution network, the aggregate transmission and commercial losses are estimated to be 26%. Judging from the trend of 2000 onwards, India’s coal consumption would have been 710 million tons in 2013 – almost twice the consumption in 2000 (359 mt) and more than three times the consumption in 1990 (224 mt).

To have allowed 26% of the generated electricity in 2013 to be ‘lost’ amounts to wasting the coal that was burned to generate it, and this is a gigantic sum, an amount equal to the 189 mt that India consumed in 1986. Secretary Pradeep Kumar Sinha, Additional Secretaries R N Choubey and Devendra Chaudhry, Joint Secretaries Mukesh Jain, B N Sharma, Pradeep Kumar, Satish Kumar and Jyoti Arora, and Economic Adviser Raj Pal must practice thrift and saving instead of entertaining industry’s demands for more power plants.

(2) India has for the last year consumed crude oil at the rate of about 3.5 million barrels a day and of this astounding amount 2.5 million barrels are imported. For 2013-14 (until 31 March) India’s appetite for crude oil cost US$ 143 billion (which represented 32% of India’s total imports for the financial year, according to the Ministry of Commerce). The standard oil barrel contains 159 litres of crude oil and, according to the Society of Petroleum Engineers, a barrel of crude oil represents about 1,700 kWh of electricity. Judging from the power consumption trend from 2000, our per capita average annual electricity consumption in 2014 will be 750-760 kWh, which is about 62 or 63 units a month.

Thus a single barrel of imported (or domestically produced) crude oil contains energy enough to supply two persons for a year, at current annual averages. Such a comparison between fuels is useful to illustrate what the country’s automobile addiction costs in terms of what it takes to furnish households with electricity. About 47% of the oil is used (after refining and being turned into various petroleum products) for transport, supporting an automobile industry that has placed 17.56 million cars, 2.01 million taxis, 3.9 million jeeps, 4.24 million light motor vehicles, 1.29 million buses, 7.37 million goods carriers, 9.42 million other vehicles (tractors, three-wheelers and so on), and 115.41 million two-wheelers, on our roads to congest our towns and cities into paralysis.

The oil import bill is Rs 872,300 crore, a number that defies the citizen’s attempts to size it (it is more than ten times the wages paid through MGNREGA (about Rs 78,106 crore) for the last three years for which 235.5 million people were provided wage employment). Goyal and his officials are therefore better advised to pay attention (together with cabinet colleague Nitin Gadkari, the minister of road transport and highways) to the 119,209 state transport buses in Bharat and India in which we travelled (economically and fairly reliably, round the clock too) some 552 million passenger kilometres.

(3) This NDA-BJP government in its first three months has blundered just as much as its predecessor government did on matters that concern every citizen: the environment, energy, the provisioning of agriculture and food, and human development. At every turn Goyal’s cabinet colleagues, and in particular Arun Jaitley, minister of finance and defence, have chanted out the tiresome refrain that India will grow, must grow, must build, must consume, must produce and so on. Their obduracy in the face of evidence to the opposite – evidence that has been available in Bharat and internationally from the time they were students, certainly – is just as tiresome. Gathering ever more citizens into the club of the urban middle class will only lead to a financial and technological trap from which there is no escape.

Coal India's share price for the last two years.

Coal India’s share price for the last two years.

One example amongst many illustrates why, quite starkly. Since 2004, the sale of room air-conditioners has grown at about 15% per year, and the industry reported sales of over 3.5 million air-conditioners in 2013. Concerned by the demand for electricity from homes and offices fitted, over the last three years, with new air-conditioners, the Bureau of Energy Efficiency (a statutory body under the Ministry of Power) set out to estimate what effect millions of new air-conditioners would have on peak electricity demand. The answer was provided by an ‘expert group on low carbon strategies for inclusive growth’ for the Planning Commission and independent analysis conducted by the Lawrence Berkeley National Laboratory (of the USA). This study found that peak electricity demand would rise by 75,000 MW to reach 150,000 MW by 2030. That is, in 15 years the peak electricity demand alone will be 60% of today’s total power generation capacity in India!

There is no financial fix and there is no technological fix for such a trend. There is no further excuse for the NDA-BJP government and for ministers like Goyal, Jaitley, Javadekar, Gadkari (and prime minister Modi) to continue to ignore the obvious. Goyal and Jaitley both need an immediate refresher in revisiting the reasons why the marginal cost curve of any action they have announced in the last three months will rise steeply. That rise will be due to a combination of activities, and the natural consequences, which will ruinously amplify the impacts of a changing climate. Bharat cannot continue to shirk the duty – of government and of citizen – of caring first for our ‘prakruti’ (what the west has recently begun to call ecological services) and instead pursuing the ‘maya’ of continuous growth.

Holding our breath in India’s cities

May 10, 2014 by Climate portal editor Leave a Comment

On the PM 2.5 scale, India's cities are easily amongst the world's riskiest places in which to live

On the PM 2.5 scale, India’s cities are easily amongst the world’s riskiest places in which to live

The findings by the World Health Organisation on the quality of air in India’s cities are the strongest signal yet to our government (old and new, for the results of the 2014 general election will become known on 16 May) that economic ‘growth’ is a weapon that kills citizens through respiratory tract diseases and infections.

Amongst the 124 Indian cities in the new WHO database on urban air quality worldwide, one city only is at the WHO guideline for PM2.5 and one city only is just above the guidelines for PM10. As a bloc, the quality of air in India’s cities are at alarmingly high levels above the guidelines, above Asian averages (poor as they are, and even considering China’s recklessly poor record) and above world averages.

This is not a singular matter. Already, the WHO has warned that India has a high environmental disease burden, with a significant number of deaths annually associated with environmental risk factors. The Global Burden of Disease for 2010 ranked ambient air pollution as the fifth largest killer in India, three places behind household air pollution. Taken cumulatively, household and ambient air pollution constitute the single greatest risk factor that cause ill health -leading to preventable deaths – in India.

The WHO database contains results of ambient (outdoor) air pollution monitoring. Air quality is represented by ‘annual mean concentration’ (a yearly average) of fine particulate matter (PM10 and PM2.5, which means particles smaller than 10 or 2.5 microns). The WHO guideline values are: for PM2.5 – 10 micrograms/m3 annual mean; for PM10 – 20 micrograms/m3 annual mean. The two charts show just how dangerously above the WHO guidelines the air quality of our cities are.

Without urgent and stringent curbs on the consumption of fuel, Indian cities' PM 10 measures will worsen

Without urgent and stringent curbs on the consumption of fuel, Indian cities’ PM 10 measures will worsen

Half of India’s urban population lives in cities where particulate pollution levels exceed the standards considered safe. A third of this population breathes air having critical levels of particulate pollution, which is considered to be extremely harmful. “We are also running out of ‘clean’ places. Small and big cities are now joined in the pain of pollution,” commented Down To Earth, the environment magazine.

Typically, the official Indian response was to question the WHO findings (these were carried out in the same way in 91 countries, and we don’t hear the other 90 complaining) and to reject them. The reason is easy to spot. Global offender Number One for air pollution amongst world cities is New Delhi, a city that has been pampered as the showcase for what the Congress government myopically calls “the India growth story”.

Hence government scientists are reported to have quickly said that WHO overestimated air pollution levels in New Delhi. “Delhi is not the dirtiest… certainly it is not that dangerous as projected,” said A B Akolkar, a member secretary of the Central Pollution Control Board.

The same recidivist line was parroted by Gufran Beig, chief project scientist at the Indian Institute of Tropical Meteorology (which otherwise does good work on the monsoon and on climate change). He is reported as having said that New Delhi’s air quality was better than Beijing’s, and that pollution levels in winter are relatively higher in New Delhi because of extreme weather events. Beig said: “The value which has been given in this (WHO) report is overestimating (pollution levels) for Delhi … the reality is that the yearly average is around 110 (micrograms).”

The WHO database has captured measurements from monitoring stations located in urban background, residential, commercial and mixed areas. The world’s average PM10 levels by region range from 26 to 208 micrograms/m3, with a world average of 71 micrograms/m3.

PM affects more people than any other pollutant. The major components of PM are sulfate, nitrates, ammonia, sodium chloride, black carbon, mineral dust and water. It consists of a complex mixture of solid and liquid particles of organic and inorganic substances suspended in the air. The most health-damaging particles are those with a diameter of 10 microns or less, which can penetrate and lodge deep inside the lungs. Chronic exposure to particles contributes to the risk of developing cardiovascular and respiratory diseases, as well as of lung cancer.

Central and state governments show no inclination to join the obvious dots. These are, that with more fuels being burned to satisfy the electricity and transport needs of a middle class now addicted to irresponsible consumption, the ‘India growth story’ is what we are choking to death on.
