Sustainable energy is the provision of sustainable use of energy resources. It ensures that the energy need and demand of the present generation is met without compromising the need of future generations. Renewable source of energy is one of the few technologies which help in promoting the concept of sustainable energy. Renewable energy includes the energy generated from renewable sources like hydro electricity, tidal electricity, solar energy, wind, geothermal etc. Energy efficiency and renewable energy together are regarded as the building blocks of sustainable energy. Sustainable energy is concept of laying dynamic harmony between the present and future generation. It is important that we find proper solution to sustainable energy sources which is more efficient. We should convert and utilize the source so that the aim of development in achieved in a better manner.
Read about Pros and Cons of Renewable Energy.
Thus we can say any energy generation source which is effective, conservative and is renewable with an ability to scale massively for long term will only help in sustainable energy. Currently there is a need of energy which is replenishable within a human lifetime and causes no damage to man and environment.
In order to meet the rising demand of current generation there is a need to utilize the power of renewable energy. There is a need to explore the green energy technology which can be extracted, generated and consumed without any significant negative impact to the environment. It is important that people understand their priority, understand their need and accordingly adapt to renewable energy which is an essential contributor to sustainable energy. Renewable energy has been regarded as a contributor to world energy security and thus it is important that their power is identified by the industrialists. It is a known fact the current consumption of energy is mainly dependent on fossil fuel which is anyways depleting at a faster rate. We should now reduce the dependence on fossil fuel resource and provide opportunity for mitigating greenhouse gases.
Talking of renewable source of energy we see that we have 3 generations of energy sources developed in different phases.
i) The first generation includes hydro power, biomass, geothermal heat etc. These technologies were widely used in 19th century.
ii) Gradually second generation evolved which includes solar heating and cooling, wind, bio energy etc. These sources are currently under research and development.
iii) Third generation is new area to exploit which includes advanced biomass gasification, ocean energy, nanotechnology etc. These sources may play a major role in shaping the need and demand of energy while minimizing the burden to the environment.
The first and second generation technologies have entered the markets where as the third generation sources depend on the research and development collectively from the public and private sector.
The economy world wide has been growing at a tremendous pace and requires utmost attention when it comes pollution. Use of private vehicles has been increasing manifold which is undoubtedly a matter of pride for nation, but again is depleting the ozone layer through harmful emissions. It is thus important to identify such energy sources for vehicles which are green and low on emission. The move will definitely take us closer towards energy sustainability. However, it definitely require changes not only in the way of energy generation but also way if its use and dissipation.
Conclusion
It is important that the government take proper steps and help the private sector develop the industry. Renewable energy now requires proper commitment and is no longer niche sectors that are promoted only by government. The increased investment required in the sector is one of the reasons; it should be made open to private players. Government should make the rating of appliances in terms of energy stars mandatory which will help people get educated about environmental impact.
At last to conclude we can say, it is the time one should stop being selfish and star thinking collectively for the coming generations too. We need to act NOW as it’s always NOW or NEVER.
