Energy is at the heart of the climate challenge – and key to the solution. A large chunk of the greenhouse gases that blanket the Earth and trap the sun’s heat are generated through energy production, by burning fossil fuels to generate electricity and heat. Fossil fuels, such as coal, oil and gas, are by far the largest contributor to global climate change, accounting for over 75 percent of global greenhouse gas emissions and nearly 90 percent of all carbon dioxide emissions.
