The science is clear: to avoid the worst impacts of climate change, emissions need to be reduced by almost half by and reach net-zero by To achieve this, we need to end our reliance on fossil fuels and invest in alternative sources of energy that are clean, accessible, affordable, sustainable, and reliable. Renewable energy sources — which are available in abundance all around us, provided by the sun, wind, water, waste, and heat from the Earth — are replenished by nature and emit little to no greenhouse gases or pollutants into the air. Fossil fuels still account for more than 80 percent of global energy productionbut cleaner sources of energy are gaining ground.
