Gasoline and Diesel All over the world, gasoline and diesel are the largest energy sourc- es for running vehicles of all types. They are produced by refining crude oil in oil refineries. These oil refineries emit large amounts of greenhouse gases that cause global warming. In order to curb global warming, it is necessary to save energy and start finding re- placements for these energy-dense and easily transportable fuels. Electricity Electricity is the most widely used form of energy. It became avail- able to us a few hundred years ago, and is now an integral part of our daily lives. We run our washing machines, televisions, refrig- erators, air conditioners, and other appliances, with the help of electricity. At present, it is widely generated in fossil fuel power plants. However, due to increasing pollution and decreasing fossil fuels, hydropower, wind power, solar power, and nuclear power are being used to generate energy.

● ● Energy cannot be destroyed; it just changes its form. ● ● Every year in the US, more than 2,300 million tons of carbon dioxide (CO 2 ) are produced by burning oil. Climate Facts
