Energy is at the heart of the climate challenge and key to solving it.
Most of the greenhouse gases that blanket the Earth and trap the sun's heat are produced through energy production, by burning fossil fuels to generate electricity and heat. Fossil fuels such as coal, oil, and natural gas have so far been the largest contributors to global climate change, accounting for over 75% of global greenhouse gas emissions and nearly 90% of all carbon dioxide emissions. The science is clear: to avoid the worst impacts of climate change, emissions need to be reduced by nearly half by 2030 and reach net-zero by 2050. To achieve this goal, we need to end our dependence on fossil fuels and invest in clean, accessible, affordable, sustainable, and reliable alternative energy sources. Renewable energy is all around us, provided by the sun, wind, water, waste, and geothermal heat, replenished by nature, and almost zero greenhouse gases or pollutants into the air.
