Energy Systems

Energy sectors account for roughly two thirds (~64%) of total greenhouse gas emissions contributing to global warming. This includes everything from the fuels that powers our vehicles and heat our homes to commercial and industrial consumption of electricity and fossil fuels. Our researchers model various energy-production scenarios that would allow countries to decrease their carbon footprint while meeting goals for more sustainable growth and development. They also study the policies and incentives that govern decision-making around energy sectors, including the role of foreign investment in emerging markets.

Written by Keely Swan, Center for Policy Research on Energy and the Environment

Coal-fired power plants are the second largest water user in China, requiring large volumes of freshwater for processing coal and cooling, and contribute significantly to greenhouse gas emissions. Meanwhile, wastewater treatment plants generate millions of tons of sludge that must be disposed of and reclaimed water that can be reused for other…

As China Converts to Clean Energy, Households Should Consider Using Heat Pumps to Maximize Climate, Air Quality, Economic, and Health Benefits
Jan. 4, 2022
Written by B. Rose Huber, Princeton School of Public and International Affairs
Many of China’s households still rely on small coal stoves for heat, which causes air pollution that damages health. To address these problems, the Chinese government launched a five-year “Clean Heating Plan” in 2017 with the goal of transitioning 70% of northern households away from coal and toward cleaner heating options.

As the plan…
