What is Solar Energy?

There are numerous benefits of clean energy , and it’s not just about simply being “green”. The industry is expanding and creating jobs. It also makes electricity grids more robust and improves access to energy in emerging countries. It also helps reduce energy costs. All these factors have played a role in the recent revival of renewable energy, which has seen wind and solar set new records in electricity generation.

In the last 150 years, mankind has relied heavily on coal, oil and other fossil fuels to power everything from light bulbs to cars and factories to automobiles to cars. The greenhouse gases generated by fossil fuels burning them have reached record levels.

The average temperature of the Earth’s surface is rising due to greenhouse gases trapping heat that could otherwise escape to space. Global warming is one of the signs to the onset of climate shift. Scientists use the term to describe the complex changes affecting the climate and weather systems on our planet. Climate change includes the rising temperature extreme weather events, shifting wildlife habitats and population growth, rising seas and many other impacts.

Renewables, like any other source of energy are not without their own set of trade-offs. One of these is the definition of renewable electricity. Renewable energy, in its strictest sense, is exactly what you think it is. It’s always available or according to according to the U.S. Energy Information Administration declares, “virtually unlimited.” Although, “renewable,” does not mean that it is sustainable, as are opponents to large hydropower dams or corn-based ethanol. This doesn’t mean other sources that have low- or no-emissions that also have advocates such as nuclear power and energy efficiency.

3 Examples of Renewable Energy sources

Hydropower: People have utilized the power of rivers for long periods of time to harness their power and build dams to control the flow of water. The world’s largest source of national renewable energy labs is hydropower. It is a major source of hydropower and has China, Brazil and Canada as the leading producers. While hydropower is theoretically an energy source that is clean that can be replenished by rain or snow, there are several downsides.

Large dams may cause disruption to river ecosystems and communities. This could lead to the displacement of residents and wildlife. Silt buildup can cause hydropower generation to be less efficient and damage equipment. Drought can also lead to issues. According to a study from 2018, carbon dioxide emissions in the Western U.S. were 100 megatons higher than normal over a 15-year period. This was due to utilities turning on gas and coal in order to replace the lost hydropower because of drought. Hydropower even at its full capacity is not without its emission issues because the organic matter that is decomposing in reservoirs releases methane.

Dams aren’t the only best way to harness water’s power, but so are tide and wave energy. While marine energy projects account for less than 1percent of all renewable energy however, they can produce 500 megawatts. This is a trend that has been boosted by programs such as the Saltire Prize in Scotland.

Wind Energy from wind turbines has been used to generate energy for over seven thousand years. Wind turbines, which generate electricity are now popping up throughout the world and include China and the U.S. and Europe being the most prominent. United States and Europe are the largest producers of wind energy. Between 2001 between 2001 and 2017, the world’s accumulated wind power increased by 22 times. It was 23,900 mw however, it was able to generate 539,000 megawatts.

While some may be displeased about the way wind turbines are positioned in the sky or their sound, wind energy is now more valuable than ever with its declining costs. Although most wind power is generated by onshore turbines, the majority of it is generated by offshore wind farms. Most prominently, they are located situated in U.K. and Germany. In 2016, one of the first U.S. offshore wind farms was launched within Rhode Island. Others offshore wind farms are getting more attention. Wind turbines pose a threat to birds and bats. They kill thousands of bats and birds annually, but not as many as from collisions with glass, or other threats like habitat loss or invading species. Engineers are looking for ways to make these secure for flying wildlife.

Solar: Solar cells are changing the energy industry around the globe and are being used on rooftops in homes to large-scale farms. The installed photovoltaic panel energy capacity has increased by 4,300 percent over the period between 2007 and 2017.

Apart from solar panels , which convert direct sunlight into electricity Concentrating solar power (CSP), plants also employ mirrors to concentrate solar power plants and derive thermal energy. The U.S., Japan and China are the leaders in solar transformation. However, solar requires a lot to complete. In 2017 in the U.S. generated around two percent of the electricity. Worldwide, solar thermal energy is being used for cooling and heating in the sun and hot water.
