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 resilient and expands access to energy in emerging countries. It also helps reduce energy costs. All of these factors have been a factor in the recent rise of renewable energy sources, which has seen wind and solar set new records for electricity production.

In the last 150 years, humankind has relied heavily upon oil, coal and various fossil fuels to power everything, starting from lighting bulbs, cars and factories, and from vehicles to automobiles. The greenhouse gases released by fossil fuels from burning have hit record records.

The temperature average of the Earth’s surface is rising due to greenhouse gases trapping heat that could otherwise go out into space. Global warming is one sign to the onset of climate shift. Scientists now use the term”climate change” to explain the complicated changes that affect the climate and weather systems that exist on the planet. Climate change is characterized by rising temperatures, extreme weather events shifts in wildlife habitats and increasing sea levels and many other impacts.

Like every other source of energy, have their own trade-offs. One of them are the terms used to define renewable electricity. Renewable energy, in its strictest sense, is exactly what you might believe. It’s either always accessible or, as it is described by the U.S. Energy Information Administration declares, “virtually unlimited.” But, “renewable,” does not necessarily mean sustainable . There are the main opponents to power dams, or corn-based ethanol. It doesn’t include other sources that have emission-free or low emissions that also have advocates like nuclear power and energy efficiency.

3 Examples of Renewable Energy sources

Hydropower: People have utilized the energy of rivers for centuries to harness their power, and to build dams to regulate the flow of water. The largest resource in the world for national renewable energy labs is hydropower. It is a major source of hydropower which includes China, Brazil and Canada being the biggest producers. Although hydropower could theoretically be a source of clean energy that is replenished by rain or snow, there are several downsides.

Large dams may create disruptions to the river ecosystem and communities. This could lead to displacement of residents as well as wildlife. Silt accumulation can cause hydropower generation to become less efficient and cause damage to equipment. Dry conditions can cause problems. According to a study from 2018, carbon dioxide emission levels in the Western U.S. were 100 megatons more than normal over a 15 year period. This was due to utilities switching to gas and coal to replenish the hydropower lost due to drought. Hydropower even at its full capacity is not without its emission issues because the organic matter that is decomposing in reservoirs releases methane.

Not only are dams the most efficient method to harness the power of water, but also is tide and wave energy. Even though marine energy projects produce less than 1% of all renewables, they still can produce 500 megawatts. This area has been encouraged through programs such as The Saltire Prize in Scotland.

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

While some may be displeased at how wind turbines look at the horizon, or the sounds, wind power is now an asset that is too valuable to be ignored, with its declining cost. Although most wind power is generated 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 located in Rhode Island. Other offshore projects are gaining momentum. Wind turbines pose a threat to bats and birds. They kill thousands of bats and birds every year, though less than collisions with glass or other dangers like habitat loss or the spread of invasive species. Engineers are seeking ways to make them more secure for flying wildlife.

Solar cells: Solar panels have revolutionized the energy market all over the world and are being used on rooftops in homes to large-scale farms. The world’s installed photovoltaic panel capacity for energy has grown by 4,300 percent over the 10 years between 2007 and 2017.

Apart from solar panels , which convert direct sunlight into electricity Concentrating sunlight power (CSP) plants also employ mirrors to concentrate solar power plants and derive thermal energy. It is believed that the U.S., Japan and China are leaders in the field of solar transformation. However, solar still requires a lot to be done. In 2017 it was estimated that the U.S. generated around two percent total electricity. Around the world, solar thermal energy is utilized for cooling and heating in the sun, as well as hot water.
