The International Energy Agency (IEA) found that rates of solar panel installation and electric vehicle purchases are consistent with the pace necessary to achieve net-zero emissions by 2050. The IEA also stressed that by 2030, fossil fuel demand must fall by 25%, energy efficiency of homes and vehicles must double, and methane emissions from the oil and gas industry must fall by 75%. However, despite the rapid increase in renewable energy, fossil fuels remain an important source of energy, especially in Asia.
