Using Renewable Energy Sources Helps Conserve Natural Resources – Mysuru Today
By Dr SVN Vijayendra
Athe awareness of the harmful effects of fossil fuels on the environment is increasing and pushing people to use renewable energy by replacing fossil fuels. The burning of fossil fuels is one of the reasons for global warming by releasing greenhouse gases (GHGs) and millions of premature deaths linked to climate change-triggered events and non-communicable diseases. Moreover, since fossil fuels are not infinite resources, the world must turn to renewable sources as soon as possible.
Many countries try to live as sustainably as possible in terms of energy sources. Energy consumption accounts for 75% of GHG emissions. Thus, the World Sustainable Energy Day (WSED) is observed on Sunday (February 27) across the world every year to reduce the use of fossil fuels and increase the use of sustainable renewable energy sources such as wind, solar, hydro, etc., which are without environmental hazard, safe, healthy, and durable. The theme for this year’s WSED observation is “Energy Transition – full speed ahead! » The WSED connects people and empowers them to embrace the necessary change in the use of energy resources.
Using renewable energy sources also helps preserve natural resources. Renewable energy provides reliable energy sources and fuel diversification. It improves energy security, reduces the risk of fuel spills and reduces the need to import fossil fuels. Globally, the share of renewable energy sources for power generation has increased from 26% in 2019 to nearly 28% in 2020. Yet coal and gas account for almost 60% of the world’s electricity supply.
Recently, the European Commission proposed that the emissions reduction target be set at 55% by 2030 with a net reduction target of 55% by 2030 compared to 1990 levels. This new ´Fit for 55´ package aims to put the EU on the path to climate neutrality. For this, it is essential to accelerate the transition of energy resources with the transformation of policies, technologies and markets.
Our country is the 3rd largest consumer of electricity in the world and is delighted to be the 3rd largest producer of renewable energy in the world with 38% of the energy capacity (136 GW out of 373 GW) installed in 2020 coming from sources renewable. The gasification of coal avoids the emission of toxic gases released during combustion and the end products of gasification such as methanol, DME, ammonia and ammonium nitrate which are basic elements for the energy industries and chemicals. Thus, very recently, our government has planned to adopt “clean coal technology” by coal gasification to avoid environmental pollution by setting up four coal gasification plants with each of the plants to use 100 million tons of coal per year by 2030 in the country.
Our country is also focusing on the production of green hydrogen as a sustainable energy source. It is proposed to waive the costs of transporting green hydrogen across the country for 25 years. The goal is to produce five million tonnes of green hydrogen by 2030. There are also plans to replace diesel with renewable energy in agriculture by 2024. The recent green hydrogen policy could be a game-changer in Indian renewable energy sources.
In solar power generation, our country has enormous potential to trap 5,000 trillion kWh per year of energy on the land area of our country, and most areas receive 4-7 kWh per square meter per day. Even if the Solar Photo Voltic modules cover 3% of the surface of the wasteland, we can generate 748 GW of solar energy. Recently, our country reached the 5th position in the world in the deployment of solar energy, overtaking Italy.
Solar power capacity has increased more than 11 times over the past five years, from 2.6 GW in March 2014 to 30 GW in July 2019. renewable energy, our country has set itself the goal of reaching approximately 40% of installed capacity of cumulative electrical energy. from non-fossil energy resources and reduce the emissions intensity of its GDP from 33% to 3% below 2005 levels by 2030.
When it comes to wind energy, it is interesting to note that more than 95% of commercially exploitable wind resources are concentrated in just seven states (Andhra Pradesh, Gujarat, Karnataka, Madhya Pradesh, Maharashtra, Rajasthan and Tamil Nadu). Our government has installed more than 800 wind monitoring stations nationwide. With a total installed capacity of 39.25 gigawatts in March 2021, our country currently has the fourth highest installed wind capacity in the world.
Wind power generated about 60.149 billion units in 2020-21. Our country is expected to produce 20 GW of power by 2025. In addition, the Indian government has also set a target of 5.0 GW of offshore wind installations by 2022 and 30 GW by 2030. After all , the power to save the planet for future generations belongs to consumers around the world.
