Why use alternative energy sources?
Alternative energy sources are available free of cost and do not tax the environment for their usage. Power generation through alternative sources of energy is clean and ‘green’. If we shift to use power generated from these sources, then carbon dioxide emission from the conventional energy sources will be greatly reduced, and the problem of global warming will be solved in a few years. Also the fast depleting traditional energy sources can be preserved. Along with air pollution, the use of traditional energy resources also cause soil pollution and water pollution by releasing various toxins to the land and water. This can also be controlled reasonably.
The damage that we have caused to earth after the industrial revolution is huge and we will have to take action immediately if we want to keep the planet sustainable for our future generations. The biggest leap that mankind can take to prevent further damage is to start using alternative energy sources.
This is the energy which the earth receives from the Sun. This is one of the most promising alternative energy sources, which will be available to the mankind for centuries to come. The only challenge remains to tap the solar energy in the most efficient way. The solar power generation is done by using a series of photovoltaic cells where the solar rays are converted into electricity. Apart from electricity production solar energy is also being used for heating water, cooking food etc.
Advantages of solar energy
- The source of energy is absolutely ‘free’.
- Solar power which is generated in the day time can be stored to be made available in the night time as well.
- Solar power generators can be used to generate power in rural and remote areas where there is no reach of the conventional form of energy.
- Solar power generation is quite and absolutely clean.
- Solar energy is a renewable form of energy will not deplete until thousands of years.
This is the energy developed from the wastes of various human and animal activities like the by-products and wastes from timber industry, agricultural yields, municipal solid waste etc. Out of the many alternative sources of energy this is the one which takes into account the utilization of waste material to develop energy thereby disposing them off in a profitable and effective way.
Advantages of biomass energy
- It is an environmental friendly way of energy production in which biological mass is recycled and re-used.
- The biomass will keep generating and decomposing as part of the natural biological cycle. Therefore, biomass energy is considered as a renewable source of energy.
The power of the wind is harnessed to propel the blades of wind turbine attached to an electric generator to generate wind energy. Wind energy is an effective alternative source of energy in areas where the velocity of wind flow is high.
Advantages of wind energy
- Wind energy is a clean form of energy.
- The source of power generation i.e., wind is free of cost.
- Wind energy is a renewable source of energy.
Challenges with using alternative energy sources
As promising as the use of alternative sources of energy may sound, it is still under research as to how to tap energy from these resources in the most efficient and effective way. Although small power generation systems can be put in place but power production from these resources on a large scale is still a challenge with hydroelectric power generation being an exception.
Many countries are not yet ready to move from using conventional energy sources to the alternative energy sources as it involves a huge amount to decommission the old power generation infrastructure and establish a new infrastructure. Therefore, the shift is ideal to be made in phases.
