New trend of “clean and green” renewable energy

Since Homo sapiens first walked the earth, we have been modifying the environment around us as per our convenience, which is sad, through agriculture, travel and eventually through urbanization, making urban jungle for residential purpose and commercial networks.

Human activity has had an effect on the environment for thousands of years in many ways. Such as, overpopulation, pollution, burning fossil fuels and deforestation. Some changes like cutting down trees and littering have a negative effect on animals and plants. Protecting endangered species and cleaning lakes and seas has a positive effect on the environment. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water.

Renewable energy sector is on boom now, and “green clean energy” term has been coined for it. Since the renewable energy comes from natural sources like sunlight or wind keep shining and blowing, even if availability of this energy depends on time and weather it has become the second name of clean energy. Constant innovation has brought the cost down making it rewarding in the long term. In India solar energy sector is breaking records and being integrated in many Government projects. Wind and solar are powering a clean energy revolution. Some examples of renewable energy sources are solar, wind, hydropower, biomass and geothermal energy.
The expansion in renewable energy sector is also happening at large and small scale, from rooftop panels on the home to schools to hospitals to factories. In some of the rural areas the entire rural community rely on renewable energy for their daily needs. Now that we have increasingly innovative and less-expensive ways to capture and retain solar energy, renewable energy is becoming a more relevant alternative and important power source. As it continues to grow, a key goal will be to modernize Indian national power grid, making it more secure, powerful and better integrated across all states in India.
The sun has provided warmth during the day and helped kindle fires to last into the evening. But over the past 500 years or so, human beings have increasingly turned to cheaper, dirtier energy sources such as coal and fracked gas. While renewable energy is often thought of a new technology, harnessing nature’s power has long been used for heating, transportation, lighting and more.
Now, what is non-renewable energy which is increasingly displacing the dirty fuels. There are different types of renewable energy sources and we can use them for our betterment at home.

Solar energy:

We humans have been harnessing solar energy for our benefits for thousands of years to stay warm, dry foods, to grow crops and preserve foods etc. According to a research conducted in National Science Lab “more energy from the sun falls on earth in one hour than is used by everyone in the world in one whole year.” Today solar energy has become one of the biggest sources of our income and to heat homes, to warm water and power our electronic devices.
Solar cells or technically we say photovoltaic cells are made from silicon or other materials that transform sunlight directly into electricity. Distributed solar systems generate electricity locally for homes and businesses, either through rooftop panels or community projects. Solar farms can generate power for thousands of homes, using mirrors to concentrate sunlight across acres of solar cells.
Solar energy systems don’t produce air pollutants or greenhouse gases, and as long as they are responsibly sited, most solar panels have few environmental impacts beyond the manufacturing process.
