India plans 5-fold increase in clean energy – Businessweek

India said Friday it was optimistic the world would reach an agreement to curb climate change, but said its actions would be focused on boosting its renewable power capacity five-fold rather than on cutting carbon emissions.

With hundreds of millions still mired in poverty and without access to electricity, India cannot afford to reduce greenhouse gas emissions at the expense of economic growth, Environment Minister Prakash Javadekar said before leaving this weekend for U.N. climate talks in Lima, Peru.

“Our growth cannot be compromised,” Javadekar said. “Poverty needs to be eradicated immediately. Poor people have aspirations. We must fulfill them. We must give them energy access. We cannot and nobody can question on this.”

He said he was optimistic industrialized nations would agree to shoulder more of the burden to reduce greenhouse gas emissions, given that they had been polluting with fossil fuels for decades before developing nations.

“That is the just regime,” he said.

The recent U.S.-China pact announcing new targets for fossil fuel use marked a positive step toward establishing this sort of equality, he said. In that pact, the U.S. said it would aim to bring down its per-capita emissions from about 20 tons while allowing China to raise its 8-9 tons per capita so that both reach a level of about 12 tons by 2030.

“They have accepted the differentiated responsibility and the need of time for growth,” Javadekar said.

India had already pledged to reduce its emissions intensity — how much carbon dioxide it produces divided by its GDP — rather than promising to cut overall emissions. However, Indian officials and scientists say it could easily go beyond the target set in 2009 of cutting emissions intensity by 20-25 percent below 2005 levels by 2020.

India’s preference for the per-capita emissions calculation also ignores the fact that around 400 million Indians still have no access to electricity at all, while hundreds of millions more are lucky to get a couple of hours a day. Experts worry that as India’s population continues to grow beyond 1.2 billion and more people become wealthy, its share of global emissions will skyrocket.

Water Shortages Will Limit Global Shale Gas Development – Businessweek

If all the world’s theoretically recoverable shale gas could be developed, our supply of clean-burning natural gas would expand 47 percent—lowering both greenhouse gas emissions and energy prices, according to estimates from the Washington-based World Resources Institute.

The hitch is that the process for extracting shale gas, called hydraulic fracking, sucks up as much as 25 million liters (6.6 million gallons) of water for each well. A report from WRI (PDF), “Global Shale Gas Development: Water Availability and Business Risks,” released on Tuesday, shows that roughly 38 percent of the world’s shale gas and oil lies buried beneath water-stressed regions. This means that extraction efforts will be difficult and expensive, as well as economically and environmentally risky.

China has the world’s largest estimated deposits of shale gas (1,115 trillion cubic feet), according to studies by the U.S. Energy Information Administration. Yet China is also one of the world’s most naturally water-stressed nations: It is home to a fifth of the world’s population but only 7 percent of its freshwater resources. WRI’s team compared maps of China’s potential shale plays with available water and found that 61 percent of China’s shale lies in arid regions. (China recently slashed in half its mid-term projections for shale gas development, from a goal of over 60 billion cubic meters annually to 30 billion cm by 2020.)

China’s Synthetic Natural Gas Plants Could Accelerate Climate Change – Businessweek

Northern China’s reliance on burning coal for heat and energy contributes to the heavy haze that shrouds city buildings, especially in winter, and shortens the life spans of northerners as compared with their southern counterparts by as much as five years, according to a recent study (PDF) in the Proceedings of the National Academy of Sciences.

A worker moves coal briquettes onto a pedicab at a coal distribution business in Huaibei, central China's Anhui province on January 30, 2013.

Beijing and other Chinese cities won’t see frequent blue skies until coal burning is dramatically curtailed in adjacent industrial regions. In September, China’s State Council released a significant new environmental target: trimming coal’s contribution to overall energy output from 67 percent in 2012 to 65 percent in 2017, even as the country’s economy and energy demand continue to grow.

STORY: Growing Concerns About Pollution And Public Health In China

Unfortunately, one scheme to limit coal burning by converting China’s plentiful coal supplies into synthetic natural gas (SNG) presents a host of other ecological worries. To date, China’s government has approved construction of nine large SNG plants in northern and western China, which are projected to generate 37 billion cubic meters of gas each year when completed. At least 30 more proposed plants are awaiting approval.

None of these planned plants are located near large Chinese cities, so the emissions generated in producing the gas will not hang directly over metropolises. But that doesn’t mean the coal-to-gas conversion process is clean. According to a new study (PDF) in Nature Climate Change, the entire life cycle of harvesting coal and turning it into gas produces from 36 percent to 82 percent more total greenhouse gas emissions than burning coal directly—depending on whether the gas is used to generate electricity or power vehicles.

While the most-polluting stages of energy generation could be moved farther from China’s population centers—perhaps allowing for more brighter, cleaner days in Beijing—the net effect could be to accelerate global climate change, argue the study’s authors, Chi-Jen Yang and Robert Jackson of the Nicholas School of the Environment at Duke University.

* China to Spend $27 Billion on Emission Cuts, Renewables

Scientific American: “China’s central government plans to spend 170 billion yuan ($27 billion) this year to promote energy conservation, emission reductions and renewable energy, the Ministry of Finance said in a statement on its website on Thursday.

The ministry said China plans to promote more use of energy-saving products and low or no-emission power generation such as solar and wind. It also wants to accelerate the development of renewable energy, as well as energy-saving technologies, such as electric and hybrid cars.

China is the worlds biggest emitter of carbon dioxide CO2, followed by the United States. A report by the International Energy Agency IEA on Thursday said China spurred a jump in global CO2 emissions to their highest ever recorded level in 2011, offsetting falls in the United States and Europe.

However, its CO2 emissions per unit of GDP, or its carbon intensity, fell by 15 percent between 2005 and 2011, the IEA said, suggesting the world’s second-largest economy was finding less carbon-consuming ways to fuel growth.

Longer term, China is targeting cuts to its 2020 greenhouse gas emissions by 40-45 percent compared with 2003 levels and aims to boost its use of renewable energy to 15 percent of overall energy consumption.”
