What is Solar Energy?
The sun’s power, or solar energy is the largest energy source on Earth. Solar power can be harnessed to produce thermal mass, or electrical energy for your business, home and utility bills. Being a renewable resource solar energy is an essential component of our future clean energy.
The sun does much more than just provide sunlight during the daylight. Every single photon of sunlight which is absorbed by Earth contains energy which fuels the planet. The ultimate source of all weather solar energy sources and solar systems, solar energy systems, are responsible for nearly every hour of the world’s energy consumption.
Where does the energy that we have come from? Our sun, as with all stars in the universe is a gigantic nuclear reactor. Massive amounts of energy is generated by nuclear fusion processes in the Core of the sun. This energy radiates into space as light and heat from the planet’s surface.
Solar thermal mass collectors as well as photovoltaics harness the power of sunshine to convert sunlight into energy usable. Even though solar energy systems account for only a small percentage of energy consumption worldwide however, the increasing cost of solar panels means that more people can benefit from the technology. Solar energy systems are a renewable, clean energy resource that will play an important role in the future of energy in the world.
What is the process of solar energy and what does solar power do?
There are many ways to harness the power of the sun. Photovoltaics and solar thermal capture are two of the most popular ways to harness the power of the sun. Photovoltaics are a more common choice for smaller-scale electric grid projects, such as solar panels for residential use. Solar thermal capture is usually utilized to generate electricity in utility solar plants. Solar thermal projects with lower temperatures can also generate electricity. They are also able to heat and cool.
Photovoltaic cells are gaining momentum and will become one of the cheapest and most rapidly increasing source of power in the near future. The advantages for solar cells are increasing every year. This will add to the environmental benefits of making use of renewable energy sources.
Photovoltaic solar energy
Photovoltaic (PV) also known as solar photovoltaic is a common way property owners can profit from the sun’s energy. A solar PV system converts sunlight into electricity. The solar panels can be stored in a battery or transmitted to the grid to receive the credit to your electricity bill.
Photovoltaic effect refers to a process where solar panels convert sunlight into electricity. The photovoltaic effect happens when sunlight hits a semiconductor material like silicon. It frees electrons and generates an electric current that can then be recorded using wiring. This current is referred to as direct current (DC), and it must be converted into alternating current (AC), electricity by a solar converter. This is necessary because the majority of household appliances in . The electric grid is powered by AC electricity.
Photovoltaics capture solar energy at many scales. Installing solar panels is an effective method to cut down your dependency of fossil fuels, and also reduce your electric cost. Photovoltaic solar energy generation can also benefit large companies as well as electric utilities. Large solar arrays can generate power to the electrical grid or power operations.
Another way to make the most of sunlight is take advantage of the sun’s heat and then use it in many different ways. While solar thermal energy can be more versatile than photovoltaic, it’s just not as efficient to use on a an insignificant scale for electricity generation like photovoltaics.
There are three types that solar thermal energy can be used Low-temperature power is used to heat and cool; mid-temperature is used to heat water, and high temperatures are used to generate electricity.
Low-temperature solar thermal systems use the cooling and heating to control the climate. Passive solar design for buildings is an example of this type. Passive solar energy happens when sunlight’s radiations can enter an area of living in order to warm it. Then, they are blocked to cool it.
Heating systems for hot water from solar can be an alternative to mid-temperature solar thermal energy systems. A solar hot water system captures heat from the sun by using collectors that are mounted on your roof. The heat is transferred to the water pipes in your home and you won’t have to rely on conventional heating methods such as gas or oil-powered water heaters.
For generating larger amounts of electricity high-temperature solar thermal energy systems are used. A solar thermal electricity plant makes use of mirrors to concentrate the sun’s rays onto tubes that contain a liquid that retains the heat energy efficiently. The heated liquid can be used to heat steam and water, which can then turn an engine into electricity. This technology is sometimes referred to as concentrating solar power.
Why is it good to use Solar Energy?
1. Solar Energy is Good for the environment
The sun is an alternative energy source. Solar energy does not produce carbon dioxide, as opposed to fossil fuels. Solar energy is more sustainable than other energy sources.
Our planet is contaminated by fossil fuels such as coal, oil, and natural gas. They release huge quantities of greenhouse gases into the atmosphere when they are burned. These include:
- Carbon Dioxide
- Nitrous Oxide
Greenhouse effect that is a major contributor to climate change, is caused by greenhouse gases. They pollute our air and cause the pollution of the air. They can be sucked out by using solar energy instead of fossil fuels. It’s therefore better for the environment, and reduces the negative impact of climate change.
2. The Sun is renewable
The sun will burn for as long as there is enough earth available to support it. Therefore, it can be considered as a source of energy that is renewable. It is guaranteed to never run out, which means you can make use of it every day.
Solar, wind and geothermal power are all vital in reducing our dependence on non-renewable resources. The day will come when we end up running out of oil gas, and coal. This is a good thing since we are able to always count on solar power.
3. Solar Power Can Increase Energy Security
Energy security refers to a country’s capability and ability to control its supply of energy. The majority of countries have to purchase at least some of their energy requirements. Low energy security is a situation in which the country is heavily dependent on foreign energy sources.
Because it is crucial to the nation’s economic growth Energy security is essential. A country that has good energies security will be less vulnerable to external influences that can increase the cost of energy-related commodities. Wars and conflicts are the most common factors that increase the cost of energy and can lead to economic harm.
A country can improve the security of its energy by making use of greater solar power. Large-scale solar cell deployment has been a huge success in nations like India and China. A large number of European countries have witnessed an rise in the production of solar energy.
4. It is believed that the Solar Industry creates jobs
Globally the solar photovoltaics market supported over 3.6 million jobs in 2018. These data are taken from a 2019 report of the International Renewable Energy Agency (IRENA). It is focused on jobs in renewable energy.
China is the largest employer, accounting for 31% the jobs. Japan is next with 7%, Germany at 5.5%, and in the United States at 4.4%. From an economic perspective it is vital that the solar industry is able to support such a large number of jobs all over the world.
5. There are many uses for solar energy.
We’ve talked about solar panels for power generation. However, solar energy could also be used for different purposes in addition to electricity generation.
The sun’s energy can be used to warm water using solar thermal technology. Solar energy doesn’t have to be utilized for the purpose of generating electricity. Many homeowners have set up solar thermal collectors, solar panels and even solar collectors in order to maximize the solar energy benefits.
6. It could reduce your energy costs.
Solar energy can reduce, or even eliminate your energy bills. Many homeowners opt to install solar power systems to take advantage of this. It doesn’t matter whether you make use of the sun to heat water or generate power, you can reduce the cost of your utilities.
This is among the main benefits of solar energy and has transformed many lives around the globe.
7. Active Solar Technologies offer a return on investment
Solar power can reduce your utility bills is related to its ability to could also generate a return on investment. In the event that the price you pay for the the technology is greater than the amount you’ll be paying in the long run, it’s not worth reducing the cost of your utilities.
Both solar electricity and solar hot water systems can give you a return on investment (ROI) in the duration all of the time. Although this is a process that requires thorough research and a favorable environment, ROI can be achieved in a variety of locations around the globe. Before you invest in these systems, make sure to find an expert installer.
8. There are many more beneficial effects of the sun's natural sun
The natural benefits that the sun brings to our planet is last on our list of priorities. This is an important element that is often overlooked, but it’s something we have to be aware of.
Many ways the sun is a supporter of living things on Earth. It is vital for the development of crops, as well as supporting the habitats and needs of living creatures.
Another term for Solar Energy is Renewable energy
Renewable energy is frequently cited as a top solution to mitigate the negative effects of rising temperatures. This is due to the fact that renewable sources like wind and solar don’t emit carbon dioxide or other gas emissions that contribute to global warming.
There are many benefits to clean energy beyond simply being “green”. This sector is growing and creating jobs. It also makes the electricity grid more durable and increases access to energy for those in developing countries. It also helps reduce energy prices. These factors have all contributed to the recent revival of renewable energy, with solar and wind setting new records for electricity production.
Over the last 150 years, mankind has relied heavily upon coal, oil and various fossil fuels for powering everything, including light bulb to automobiles and factories to vehicles to automobiles. The greenhouse gases generated by fossil fuels burning have hit record levels.
The temperature average of the earth’s surface is increasing due to greenhouse gases trapping heat that could otherwise escape to space. Global warming is one sign of climate change. Scientists use the term”climate change” to describe the complex changes affecting the weather and climate systems on our planet. Climate change can be described as increasing temperatures extreme weather events, shifting wildlife habitats and population growth, rising seas and a myriad of other effects.
Like any other energy source, have their own trade-offs. One of them is the definition of renewable electricity. Renewable energy, in its strictest sense is precisely what you would expect. It is either perpetually available or according to the U.S. Energy Information Administration says, “virtually unlimited.” Although, “renewable,” does not mean that it is sustainable, as are opponents to large hydropower dams or corn-based ethanol. It doesn’t include other resources with low- or no-emissions that also have advocates like nuclear power and energy efficiency.
3 Examples of Renewable Energy sources
Hydropower: Humans have used the power of rivers for many centuries for harnessing their potential and construct dams to regulate the flow of water. The biggest source of national renewable energy laboratories is hydropower. It is a major source of hydropower which includes China, Brazil and Canada being the biggest producers. Although hydropower can theoretically be a source of clean energy that is replenished through snow or rain however, there are a few drawbacks.
Large dams can cause disruption to river ecosystems and communities. The result could be the displacement of residents and wildlife. Silt accumulation could cause hydropower generation to be less efficient and damage equipment. The drought can also cause problems. According to a study in 2018, carbon dioxide emissions in the Western U.S. were 100 megatons higher than normal over a period of 15 years. This was due to utilities turning on gas and coal to replace lost hydropower because of drought. Hydropower even at its full capacity, has emissions issues as the decaying organic material in reservoirs releases methane.
Dams are not only the best way to harness the power of water, but also is tide and wave energy. Although marine energy projects generate less than 1percent of all renewable energy, 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 as a source of energy for more than 7,000 years. Wind turbines that generate electricity are now popping up all over the world, with China as well as the U.S. and Europe being the most prominent. United States and Europe are the largest producers of wind power. Between 2001 to 2017 the world’s total wind power increased by 22 times. It was 23,900 mw, but it could generate 539,000 megawatts.
Although some might be unhappy at the way wind turbines appear on the horizon or their noise, wind energy is now more valuable than ever because of its falling costs. While the majority of wind power is generated from onshore turbines most of it comes from offshore wind farms. The most prominent being those in U.K. and Germany. In 2016, one of the first U.S. offshore wind farm was inaugurated located in Rhode Island. Other offshore projects are growing in popularity. Wind turbines pose a risk to birds and bats. They kill thousands of bats and birds annually, but less than collisions with glass or other dangers such as habitat destruction and invasive species. Engineers are searching for ways to make them more safe for flying wildlife.
Solar: Solar cells have revolutionized the energy market all over the world, from rooftops on homes to huge-scale farms. The photovoltaic panel’s installed 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 sunlight 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 leaders in solar transformation. However, solar needs a lot to do. In 2017, the U.S. generated around two percent of the electricity. In the world, solar thermal power is utilized for cooling and heating in the sun and hot water.
