What is Green Energy..?
Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.Renewable energy often provides energy in four important areas: electricity generation, air and water heating/cooling, transportation, and rural (off-grid) energy services.
Renewable energy resources exist over wide geographical areas, in contrast to other energy sources, which are concentrated in a limited number of countries. Rapid deployment of renewable energy and energy efficiency is resulting in significant energy security, climate change mitigation, and economic benefits.
Benefits of Renewable Energy..
-Environmental and economic benefits of using renewable energy include:
-Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution
-Diversifying energy supply and reducing dependence on imported fuels
-Creating economic development and jobs in manufacturing, installation, and more
The most common renewable power technologies include:
-Solar (photo voltaic, solar thermal)
-Wind
-Bio gas (e.g., landfill gas/waste water treatment digester gas)
-Geothermal
-Biomass
-Low-impact hydroelectricity
-Emerging technologies - wave and tidal power
Why Green Energy is required..?
Climate change and global warming concerns, coupled with high oil prices, peak oil, and increasing government support, are driving increasing renewable energy legislation, incentives and commercialization. New government spending, regulation and policies helped the industry weather the global financial crisis better than many other sectors.According to a 2011 projection by the International Energy Agency, solar power generators may produce most of the world's electricity within 50 years, reducing the emissions of greenhouse gases that harm the environment.
World Scenario :
At the national level, at least 30 nations around the world already have renewable energy contributing more than 20 percent of energy supply. National renewable energy markets are projected to continue to grow strongly in the coming decade and beyond.Some places and at least two countries, Iceland and Norway generate all their electricity using renewable energy already, and many other countries have the set a goal to reach 100% renewable energy in the future. For example, in Denmark the government decided to switch the total energy supply (electricity, mobility and heating/cooling) to 100% renewable energy by 2050.At least 47 nations around the world already have over 50 percent of electricity from renewable resources.
Green Energy in India..
Renewable energy in India comes under the purview of the Ministry of New and Renewable Energy (MNRE). India was the first country in the world to set up a ministry of non-conventional energy resources, in the early 1980s. Solar Energy Corporation of India is responsible for the development of solar energy industry in India. Hydroelectricity is administered separately by the Ministry of Power and not included in MNRE targets.
Renewable energy do not emit greenhouse gases in energy generation processes, making them the cleanest, most viable solution to prevent environmental degradation.Also Compared to conventional energy sources such as coal, gas, oil and nuclear - reserves of which are finite - clean energies are just as available as the sun from which they originate and adapt to natural cycles, hence their name “renewables”. This makes them an essential element in a sustainable energy system that allows development today without risking that of future generations.
Finally we can say we have to switch to green energy completely to save our mother earth.
