ALTERNATE SOURCES OF ENERGY NAME:S.SHIVA THARUN SECTION:9th ‘F’ Alternative Forms of Energy Alternative energy is energy that is neither based on fossil fuels nor on the splitting of atoms. The reason is that both these forms of producing energy have damaging effects on environment. Fossil fuels ingest harmful gases in the environment and the splitting of atoms (nuclear energy), produces radioactive waste. Keeping in mind the vast damage non-renewable energies have caused to our earth, the option we are left with is using alternative energy sources. Alternative Forms of Energy / Sun Solar energy is all about using natural sunlight. Widely and freely available to almost all of humankind, the light from the Sun is a natural alternative. Solar energy is ultimately the source for many renewable and non-renewable energy sources. Energy from the sun is captured through a solar panel. A solar panel is typically made up of silicon. And silicon is the substance which absorbs sunlight and then changes it into electrical energy. And the energy you get costs nothing and is renewable. Solar energy is renewable for sure, but isn’t constant. It can only be reaped during daytime. The other concern is only fifty percent of energy received by a solar panel can be converted into electricity. Alternative Forms of Energy / Wind A typical windmill is a huge fan-like standing structure. Wind is of use to us because of its kinetic energy. The wind blows and the blades of the mill spin, which in turn power a generator. These energy harvesters work easily and they can be set up anywhere. Needless to say, the source of energy is clean and renewable. Wind is all that is needed to reap the benefits. A windmill emits nothing harmful, which means no greenhouse gas contribution to the atmosphere. The pace at which wind energy is being reaped is comparatively slow.
