What is Solar Energy?

There are many advantages to clean energy , and it’s not just about simply being “green”. The industry is expanding and is creating new jobs. It also makes electricity grids more robust and improves access to energy in developing countries. Additionally, it reduces the cost of energy. All of these factors have been a factor in the recent rise of renewable energy sources, with solar and wind setting new records in electricity generation.

Over the last 150 years, humanity has relied heavily upon coal, oil and various fossil fuels for powering everything, from light bulbs to cars and factories, from automobiles to cars. The greenhouse gasses released by fossil fuels from burning them have reached record highs.

The temperature average of the surface is rising because greenhouse gases trap heat that could otherwise go out into space. Global warming is one of the signs of climate change. Scientists are now using the term”climate change” to describe the complex changes affecting the weather and climate systems that exist on the planet. Climate change is characterized by the rising temperature extreme weather conditions, shifting wildlife habitats and populations, rising seas and other impacts.

Like any other energy source are not without their own set of trade-offs. One of them are the terms used to define renewable electricity. Renewable energy, strictly speaking, is exactly what you think it is. It is either perpetually available or according to according to the U.S. Energy Information Administration states, “virtually unlimited.” However, “renewable,” does not mean that it is sustainable, as are opponents to large power dams, or corn-based ethanol. This doesn’t mean other resources with emission-free or low emissions that also have advocates such as energy efficiency and nuclear power.

3 Examples of Renewable Energy sources

Hydropower: People have used the energy of rivers for centuries in order to tap into their energy, and to build dams to regulate water flow. The largest resource in the world for national renewable energy labs is hydropower. It is the largest producer of hydropower, with China, Brazil and Canada being the biggest producers. Although hydropower could theoretically be an energy source that is clean that can be replenished by snow or rain however, there are a few drawbacks.

Large dams can disrupt river ecosystems and communities. This could lead to the displacement of residents and wildlife. Silt buildup can cause hydropower generation to become less efficient and cause damage to equipment. The drought can also cause issues. According to a study in 2018 carbon dioxide emissions in 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 because of drought. Hydropower even at its highest capacity has its emissions problems since the organic material that decays in reservoirs emits 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 but they still are able to generate 500 megawatts. This has been made possible through programs such as the Saltire Prize in Scotland.

Wind: The energy of wind has been used to generate energy for over 7,000 years. Wind turbines, which generate electricity are now proliferating across the globe including China, the U.S. It is believed that the United States and Europe are the top producers of wind energy. Between 2001 to 2017, the world’s cumulative wind power increased by 22 times. It was 23,900 MW, but it could generate 539,000 megawatts.

Although some might be dissatisfied about the way wind turbines appear at the horizon, or the sounds, wind power is becoming more valuable than ever because of its falling prices. While the majority of wind power is generated by onshore turbines, the majority of it is generated by offshore wind farms. The most well-known are those in U.K. and Germany. In 2016 one of the first U.S. offshore wind farm was launched located in Rhode Island. The other offshore developments are gaining momentum. Wind turbines pose a threat 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 destruction and the spread of invasive species. Engineers are looking for ways to make these secure for wildlife flying through them.

Solar: Solar cells are changing the energy market across the globe, from rooftops on homes to large-scale farms. The installed photovoltaic panel capacity for energy has grown by 4,300 percent in the period between 2007 and 2017.

Apart from solar panels , which convert direct sunlight into electricity, concentrating solar power (CSP) plants also use mirrors to concentrate solar power plants, and to extract thermal energy. The U.S., Japan and China are leaders in solar transformation. However, solar still needs a lot to complete. In 2017, the U.S. generated around two percent of all electricity. Around the world, solar thermal energy is being used to power solar heating and cooling, as well as hot water.
