The energy obtained from the alternative energy sources is called alternative energy. The various alternative energy resources are solar energy, wind energy, tidal energy, geothermal energy etc. The alternative energy obtained from the alternative sources of energy is non- polluting and can be put to several uses.
The use of alternative energy resources and production of alternative energy have increased over the years. Therefore, there is a rapid rise in the number of alternative energy companies.
Fossil fuels are non-renewable sources of energy that meet most of the energy needs today. Their reserves are fast declining and we will shortly face a situation when no fossil fuels will be left. Therefore alternative energy resources are required to meet the increasing needs of energy across the globe.
Alternative energy resources do not cause pollution as opposed to the burning of fossil fuels that emits gases like carbon monoxide, sulphur dioxide etc. in the air and thus pollutes the atmosphere. Also these sources are renewable alternative energy sources that can never end.
The energy that is produced by alternative energy companies does not contribute to global warming and pollution. Alternative energy companies are working on developing energy sources that are non-polluting and do not harm the environment in any way.
To set up alternative energy companies a lot of investment is required. Also the research required for the development of alternative energy sources is expensive. These companies produce alternative energy in quantities that are sufficient enough to meet the energy requirements of the world.
