Introduction

In the last few decades, due to the ever-increasing average population of the world, modern technological developments and the increasing rate of electrification, the demand for energy has increased globally. Environmental experts believe that this demand can be met through various renewable energy options.

Importance of Renewable Energy

With the expansion of wind, water power and solar energy in the world, as well as power generation from geothermal energy, the world’s maximum power needs can be met. By adopting renewable energy, air pollution can be reduced by improving the quality of the world environment. Renewable energy sources are safe, self-sustaining and reliable, with huge amounts available year-round.

Most of the world’s energy is derived from petroleum, natural gas, wood, sunlight and uranium. In the coming few thousand years only, our traditional energy sources will be exhausted. We have finished it in a few minutes, which nature has spent millions of years in making. Environmental pollution, social and economic pressures and political upsets make the problem more serious. Therefore, the development and use of renewable energy sources and having strong will power for this is the need of the day.

This requires massive use of renewable energy as well as strengthening of its storage capacity. To adopt renewable energy voluntarily, it has to be emotionally and socially connected. To increase their credibility, more control over renewable energy resources and better performance will have to be ensured.

Government assistance of 210 billion rupees (US $ 3.1 billion) is planned to the solar panel manufacturing industry to increase India’s photovoltaic capacity. Under this scheme, India is committed to generate 40 percent of the total energy by 2030 with green energy.

Conclusion

In view of limited energy resources and high cost of imports, Prime Minister wants to focus on innovation and research in renewable energy sectors like solar and wind energy. This will provide electricity to every family at a reasonable price.


Renewable Energy Essay – 3 (400 Words)

Introduction

Renewable energy is being used as an alternative to conventional energy. Due to development of technology, renewable energy can be used easily in daily life and for commercial consumption. This type of energy does not pollute the atmosphere; hence it is also called clean fuel. This fuel or energy will never run out, it can be replenished. Unlimited reserves of renewable energy resources are available everywhere in the world. It requires less expenditure and less capital investment.

A Stable Solution to Energy Requirement

We all know that mineral and fossil fuels are rapidly ending and the day is not far when petroleum and coal will be completely extinct from the earth. Many oil wells around the world have started drying. Apart from this, many coal reserves are rapidly depleted, due to which it has become a big problem for some countries that are completely dependent on coal and petroleum for energy production.

In contrast, renewable energy sources such as sun, wind and biomass are stable and sustainable solutions for energy derived from them is very important. That is why a need to adopt these sources of renewable energy to solve energy needs. The production and use of solar energy requires photovoltaic cells and solar panels, and the production of hydroelectric power requires the construction of hydroelectric plants. Similarly, wind mills and wind turbines are required for the production of wind energy.

A Pollution-free Energy Resource

The energy generated by the combustion of fossil fuels such as petroleum, crude oil, natural gas and coal produces polluting gases and increases global warming. On the other hand, renewable energy does not cause pollution in the atmosphere.

It protects our Earth from catastrophic problems like pollution and global warming, so we need to make every effort to adopt pollution-free renewable energy generated by the sources of renewable energy.

Conclusion

At present, the entire world is largely dependent on sources of non-renewable energy, which is derived from fossil fuels like crude oil and coal. Due to which the fossil fuels are getting depleted rapidly and the oil wells of the oil producing countries are drying up rapidly and the coal mines are also coming to an end. Which is a global concern and the day is not far when fossil fuel reserves will be completely exhausted from the earth. Due to which many activities and economic activities will come to a standstill.

Long Essay on Renewable Energy – 5 (600 words)

Introduction

Such energy, which is infinite in nature and freely present, is called renewable energy. In other words, we can say that renewable energy is the energy that we get from those sources, which are available in plenty in nature. Sun, wind, and running water are sources of some energy that will never end, because they are regenerated by nature. All these renewable energies are converted and stored in the form of electricity and transported to us for our use.

Sources of Renewable Energy

Most of the world’s energy is derived from coal, petroleum, natural gas, wind, sunlight, and uranium which are non-renewable resources.

Renewable sources of energy include those sources which, once used, become usable again. Names of renewable energy sources are Sun energy, watermill energy, geothermal energy and biomass (this includes ethanol, biodiesel). According to the data released by the Ministry of New and Renewable Energy, India’s total renewable energy generation capacity is 896602 MW. India has the capacity to generate 900 GW of renewable energy from renewable energy sources such as solar energy, wind energy, hydro energy and bio-energy.

Types of Renewable Energy

Different types of renewable energy are available in this world, which provide clean and sustainable energy for our various needs. Such as wind, sunlight, and ocean are also examples of various renewable energy sources.

At the macro level, we can classify these renewable energies based on their sources.

  • Hydropower: Hydropower is the energy that is generated by stopping the flowing water of the river by building dams and driving turbines using its flow. Pumped-storage-hydropower and run-of-river-hydropower are two different ways in which electricity is produced by hydroelectric projects.
  • Bio-energy: It originates from biomass bio-energy, which is a renewable energy source for the production of liquid fuels, in which fuel is obtained from the decomposition of various types of agricultural wastes.
  • Geothermal Energy: Geothermal energy is a renewable energy that emanates from the heat inside the earth. Geothermal power plants generate electricity by absorbing the energy of earth and hot rocks. Apart from this, geothermal energy can also be used to keep water and buildings warm as per the requirement.
  • Solar Energy: This energy is generated by the heat of the sun; solar energy is produced by absorbing sunlight from all types of solar energy resources. Solar energy is a widely used as renewable energy in India.
  • Ocean Energy: Ocean energy is also one of the major sources of renewable energy, in which energy can be generated by tidal waves and ocean waves. Although there is no significant development in the field of ocean energy, but because about 70 percent of the Earth is surrounded by oceans, there is a lot of potential for energy production in this area.
  • Wind Energy: Wind energy is an excellent example of renewable energy, in which energy is produced by wind. When the wind blows in the wind turbines, renewable energy is generated by its rotational speed. For the manufacture of wind energy, large scale windmills are constructed on the seaside, where the wind blows very fast.

Conclusion

Renewable energy sources are safe, self-sustaining and reliable, with the huge amounts available throughout the year. Also, equal distribution of renewable energy is also possible. There are huge amounts of bio-mass, solar energy, wind energy, biogas and small hydroelectric producing sources in India. We have made considerable progress in the field of solar energy in the last few years, in which it has been widely publicized with the help of the government in the solar energy projects, so now the private companies in this field has also started manufacturing products like solar batteries and solar panels.
