How solar energy helps people and the environment
What is it?
Solar energy is radiant light and heat from the sun harnessed using a range of ever-evolving technologies such as solar heating, solarphotovoltaics, solar thermal energy, solararchitecture and artificial photosynthesis.
how does solar panels and will mills help you?
Solar power cells convert sunlight into electricity, using the energy of speeding photons to create an electrical current within a solar panel. Photons are created in the center of the sun by the fusion of atoms and the energy can can be used to power homes like this below
Advantages for solar energy
solar energy is free of harmful toxins and gasses and it is 100% eco friendly
It is estimated that the worlds oil reserves will last for 30 to 40 years. On the other hand, solar energy is infinite (forever). Solar energy can be used in remote areas where it is too expensive to extend the electricity power grid.
Disadvantages for solar energy
Solar collectors, panels and cells are relatively expensive to manufacture although prices are falling rapidly. Solar power stations can be built but they do not match the power output of similar sized conventional power stations. They are also very expensive. Large areas of land are required to capture the suns energy. Collectors are usually arranged together especially when electricity is to be produced and used in the same location
