There is a huge amount of energy in the sun, and solar energy is a clean energy that does not produce greenhouse gas pollution. However, because there is no direct sun exposure at night or under rainy weather, solar panels need to be used to store solar energy on sunny days. This kind of storage technology is too costly and low efficiency, which seriously hinders the process of solar energy replacing fossil fuels on a large scale. Therefore, improving the existing solar energy storage technology is the key to the development of solar energy.
The leaf is a masterpiece of nature. It has fulfilled the dream that scientists have dreamed of for many years: the use of light to split water and make fuel. This simple idea consumes a lot of energy and financial resources. The ultimate goal is of course to be full. Utilizing solar energy resources, while eliminating people’s dependence on carbon, if one-thousandth of the sun shining on the earth can be used, the energy that people have is equivalent to 9 times the energy needed.
The various technologies that promote the development of new energy have attracted more and more attention, and this is even more obvious when the Copenhagen cyclone is blowing all over the world. Chemists at MIT have invented a catalyst that can use sunlight to turn water into hydrogen. If the process can be scaled up, it can make solar energy the main source of energy. More significant is that this technology may be applicable to seawater, so people will have more choices for energy and water issues.
