What is Solar Energy?

There are numerous benefits of clean energy , and it’s not just about being “green”. The sector is expanding and is creating new jobs. It also makes the electricity grid more durable and increases access to energy in the developing world. Additionally, it reduces energy costs. All these factors have played a role in the recent revival of renewable energy sources, with wind and solar setting new records in electricity generation.

Over the last 150 years, humanity has relied heavily on coal, oil, and other fossil fuels for powering everything from light bulbs to cars and factories, from automobiles to cars. The greenhouse gases generated by fossil fuels burning them have reached record records.

The temperature average of the earth’s surface is increasing because greenhouse gases trap heat that could otherwise escape out into space. Global warming is one sign of climate change. Scientists now use the term”global warming” to explain the complicated changes that affect the weather and climate systems on our planet. Climate change includes rising temperatures extreme weather conditions shifts in wildlife habitats and population growth, rising seas and many other impacts.

Like every other energy source, have their own trade-offs. One of them is the definition of renewable electricity. Renewable energy, strictly speaking, is exactly what you might believe. It’s either always accessible or, as according to the U.S. Energy Information Administration declares, “virtually unlimited.” However, “renewable,” does not mean that it is sustainable, as are those who oppose large Hydropower Dams and corn-based Ethanol. It does not include other sources with emission-free or low emissions that also have advocates like energy efficiency and nuclear power.

3 Examples of Renewable Energy sources

Hydropower: People have utilized the power of rivers for centuries to harness their power and construct dams to regulate the flow of water. The biggest source of national renewable energy laboratories is hydropower. It is a major producer of hydropower which includes China, Brazil and Canada as the leading producers. Although hydropower can theoretically be an energy source that is clean that is replenished by snow or rain, there are several downsides.

Large dams may cause disruption to river ecosystems and communities. This can result in displacement of residents as well as wildlife. Silt build-up could cause hydropower generation to become less efficient and cause damage to equipment. Drought can also lead to problems. According to a study from 2018 CO2 emissions from the Western U.S. were 100 megatons higher than usual over a 15 year period. This resulted from utilities switching to coal and gas in order to replace the lost hydropower due to drought. Hydropower, even when it is at its maximum capacity is not without its emission issues because the organic matter that is decomposing in reservoirs releases methane.

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

Wind The energy of wind has been used for energy production for more than 7,000 years. Wind turbines that generate electricity are now thriving across the globe and include China, the U.S. The United States and Europe are the largest producers of wind power. Between 2001 and 2017, the world’s cumulative wind power grew by 22-fold. It was 23,900 megawatts however, it was able to generate 539,000 megawatts.

While some may be displeased with how wind turbines look on the horizon or their sounds, wind power is now too valuable to ignore, due to its decreasing prices. Although the majority of wind power comes by onshore turbines, the majority of it is generated by offshore wind farms. Most prominently, they are located those in U.K. and Germany. In 2016, the very first U.S. offshore wind farm was inaugurated within Rhode Island. Others offshore wind farms are also gaining momentum. Wind turbines are a danger to birds and bats. They kill thousands of bats and birds every year, though less than collisions with glass or other dangers such as habitat loss and invading species. Engineers are searching for ways to make them more safe for flying wildlife.

Solar cells: Solar panels are changing the energy market all over the world, from rooftops on houses to farms on a large scale. The photovoltaic panel’s installed 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 focus solar power plants, and to extract thermal energy. It is believed that the U.S., Japan and China are the leaders in the field of solar transformation. However, solar still needs a lot to be done. In 2017, it was estimated that the U.S. generated around two percent of the electricity. Around the world, solar thermal energy is being utilized for solar cooling and heating and hot water.
