What is being done to preserve energy?




Higher temperatures threaten dangerous consequences: drought, disease, floods, and lost ecosystems. And from sweltering heat to rising seas, global warming's effects have already begun. But solutions are in sight. We know where most heat-trapping gases come from: power plants and vehicles. And we know how to curb their emissions: modern technologies and stronger laws. NRDC is working to put these fixes in place. By shifting the perception of global warming from abstract threat to pressing reality, and promoting online activism. By pressing businesses to use less energy and build more efficient products. And by fighting for laws that will speed these advances. So scientists have found a way to renew energy. Well Renewable energy is the generation of electricity, transport fuel, process heat and other end-use forms of energy from primary sources that are not depleted by such generation. For example Solar Energy is being harvest and the thing is it is free. Usually energy is produce by nuclear plants which releases into the atmosphere carbon dioxide and the increase in greenhouse gases. But with Renewable energy nuclear plants are no longer needed.

Another type of crops is being grown. They are Drought Resistant Crops. In a few years since the heating of the planet cause by Global Warming their will be a shortage of Water Supply. So without water, human life as we know can not exist. But with Drought Resistant Crops which is made up of weed and a small amount of water hopefully if approved by consumers and scientist it can be consume without wasting water supply.
