What is Solar Energy?

There are many benefits to clean energy , and it’s not just about being “green”. This sector is growing and is creating new jobs. It also makes electricity grids more durable and increases the availability of energy for emerging countries. It also helps reduce the cost of energy. These factors have all contributed to the recent revival of renewable energy, with solar and wind setting new records in electricity generation.

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

The temperature average of the Earth’s surface is rising because greenhouse gases trap heat that would otherwise escape to space. Global warming is a sign of climate change. Scientists now use the term to describe the complex changes that affect the climate and weather systems that exist on the planet. Climate change includes rising temperatures extreme weather conditions shifts in wildlife habitats and populations, rising seas and other impacts.

Renewables, like any other energy source, have their own trade-offs. One of these are the terms used to define renewable electricity. Renewable energy, strictly speaking is precisely what you think it is. It’s always available or, as according to the U.S. Energy Information Administration says, “virtually unlimited.” However, “renewable,” does not mean that it is sustainable, as are the main opponents to hydropower dams or corn-based ethanol. This doesn’t mean other sources that have emission-free or low emissions that are also backed by advocates, such as nuclear power and energy efficiency.

3 Examples of Renewable Energy sources

Hydropower: Humans have used the energy of rivers for centuries in order to tap into their energy, 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 the largest producer of hydropower, with China, Brazil and Canada as the leading producers. Although hydropower could theoretically be an alternative source of clean energy that is replenished by snow or rain but there are many drawbacks.

Large dams can cause disruption to the river ecosystem and communities. This can result in displacement of residents as well as wildlife. Silt build-up can cause hydropower generation become less efficient and cause damage to equipment. The drought can also cause problems. According to a study from 2018, carbon dioxide emission levels in the Western U.S. were 100 megatons higher than normal over a 15-year period. This was due to utilities turning to gas and coal to replenish the hydropower lost due to drought. Hydropower, even when it is at its maximum capacity is not without its emission issues 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 so is wave and tide energy. While marine energy projects account for less than 1percent of all renewable energy, they still are able to generate 500 megawatts. This is a trend that has been boosted by programs like The Saltire Prize in Scotland.

Wind: Wind energy has been utilized to generate energy for more than 7700 years. Wind turbines that generate electricity are now proliferating across the globe, with China and the U.S. It is believed that the United States and Europe are the leading producers of wind power. Between 2001 and 2017, the world’s cumulative wind power increased 22-fold. It was 23,900 mw, but it could generate 539,000 megawatts.

Although some might be unhappy about the way wind turbines appear at the horizon, or the sound, wind energy is now too valuable to ignore, with its declining cost. Although most wind power comes by onshore turbines, the majority of it is generated by offshore wind farms. The most well-known are situated in U.K. and Germany. In 2016, the very first U.S. offshore wind farm launched in Rhode Island. Other offshore projects are getting more attention. Wind turbines pose a threat to birds and bats. They kill thousands of bats and birds every year, though they are not as numerous as collisions with glass or other dangers such as habitat loss and the spread of invasive species. Engineers are seeking ways to make them more safe for flying wildlife.

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

Apart from solar panels that convert direct sunlight to electricity Concentrating sunlight power (CSP) plants also employ mirrors to focus solar power plants and derive thermal energy. The U.S., Japan and China are the leaders in the field of solar transformation. But solar has a lot of work to be done. In 2017 the U.S. generated around two percent of the electricity. Around the world, solar thermal energy is being used for solar cooling and heating as well as hot water.
