What is Solar Energy?

There are numerous benefits of green energy that go beyond being “green”. This sector is growing and is creating new jobs. It also makes the electricity grid more durable and increases access to energy for those in developing countries. And it helps lower energy costs. All these factors have been a factor in the recent rise of renewable energy sources, with wind and solar setting new records in electricity generation.

Over the last 150 years, mankind has heavily relied on oil, coal and various fossil fuels to power everything including light bulb to automobiles and factories, from vehicles to automobiles. The greenhouse gasses produced by fossil fuels burning them have reached record records.

The temperature average of the surface is rising due to greenhouse gases trapping heat that would otherwise escape to space. Global warming is a sign to the onset of climate shift. Scientists now use the term”global warming” to describe the complex changes affecting the climate and weather systems that exist on the planet. Climate change includes increasing temperatures, extreme weather events, shifting wildlife habitats and increasing sea levels and many other impacts.

Like every other energy source come with their own trade-offs. One of them is the definition of renewable electricity. Renewable energy, in its strictest sense, is exactly what you would expect. It is either perpetually available or, as it is described by the U.S. Energy Information Administration says, “virtually unlimited.” However, “renewable,” does not necessarily mean sustainable . There are those who oppose large hydropower dams or corn-based ethanol. This doesn’t mean other resources with emission-free or low emissions that also have advocates like nuclear power and energy efficiency.

3 Examples of Renewable Energy sources

Hydropower: People have used the energy of rivers for long periods of time for harnessing their potential, and to build dams to regulate the flow of water. The biggest source of national renewable energy laboratories is hydropower. It is a major producer of hydropower, with China, Brazil and Canada being the top producers. While hydropower is theoretically a source of clean energy that is replenished by rain or snow, there are several downsides.

Large dams can cause disruption to the river ecosystem and communities. The result could be the displacement of residents and wildlife. Silt buildup can cause hydropower generation be less efficient , and also damage equipment. Drought can also lead to problems. According to a 2018 study, carbon dioxide emission levels in the Western U.S. were 100 megatons higher than normal over a 15 year period. This resulted from utilities switching on gas and coal to replace lost hydropower due to drought. Hydropower even at its highest capacity has its emissions problems since the organic material that decays in reservoirs releases methane.

Dams aren’t the only most efficient method to harness the power of water, but also is tide and wave energy. While marine energy projects account for less than 1% of all renewables but they still are able to generate 500 megawatts. This has been made possible by programs like the Saltire Prize in Scotland.

Wind The energy of wind has been utilized to generate energy for more than seven thousand years. Wind turbines, which generate electricity are now thriving throughout the world, with China as well as the U.S. and Europe being the most prominent. United States and Europe are the largest producers of wind energy. Between 2001 to 2017 the world’s total wind power grew by 22-fold. It was 23,900 mw and it could produce 539,000 megawatts.

Although some might be unhappy at the way wind turbines are positioned in the sky or their noise, wind energy is now too valuable to ignore, due to its decreasing prices. While the majority of wind power is generated through onshore turbines, most of it is generated by offshore wind farms. The most prominent being situated in U.K. and Germany. In 2016 the first U.S. offshore wind farms was opened within Rhode Island. Other offshore projects are also gaining momentum. Wind turbines pose a risk to birds and bats. They kill thousands of bats and birds each year, although not as many as from collisions with glass or other threats such as habitat loss and the spread of invasive species. Engineers are searching for ways to make them secure for wildlife flying through them.

Solar: Solar cells are changing the energy market across the globe, from rooftops on homes to huge-scale farms. The world’s installed photovoltaic panel energy capacity has increased by 4,300 percent over the period between 2007 and 2017.

In addition to solar panels that convert direct sunlight into electricity, concentrating sun power (CSP), plants also make use of mirrors to concentrate solar power plants and derive thermal energy. CSP is a popular method of generating thermal energy. U.S., Japan and China are leaders in solar transformation. But solar needs a lot to complete. In 2017 in the U.S. generated around two percent of all electricity. In the world, solar thermal power is being used for solar heating and cooling as well as hot water.
