5 Renewable Energy Resources

5 Renewable Energy Resources – Technologies such as solar and wind power are becoming common around the world, and both are examples of renewable energy. There are many ways to generate electricity from renewable sources. These fossil fuel alternatives will become an even more important part of our electricity generation mix in the coming years.

Renewable energy sources are sources of energy that are continuously replenished by natural processes. These sources are often referred to as renewable or renewable energy, mainly because they are a fuel alternative that can replace traditional non-renewable fossil fuels. Fossil fuels, such as oil and coal, produce energy when they are burned, but their supply is limited because they do not naturally replenish in the short term for human use.

5 Renewable Energy Resources

Renewable energy sources are beneficial because they have the least negative impact on the environment compared to fossil fuels. They were too expensive to be widely used. However, this is changing – many renewable energy sources are cost-effective, and some may even be a smart financial decision for homeowners, businesses and governments. In particular, solar energy is a great option for homeowners who want to reduce their environmental footprint while saving money. You can find out how much solar energy will save you while helping the environment with Energiesage’s solar calculator.

What Are The Five Major Types Of Renewable Energy?

There are five main technologies that are considered “renewable energy sources”. We’ve put together an infographic below to compare the top five renewable options side by side”:

One of the most popular forms of renewable energy is solar energy. Solar energy comes from the sun, which provides our entire planet with the energy we need to survive. By using solar panels, we can capture energy from the sun’s rays and convert it into electricity that powers our homes and businesses. Solar energy can also be used to generate hot water or install a battery system.

Solar energy has benefits for your bank account and the environment. The cost of solar continues to drop, and installing solar on your home will almost always save you money over the life of your installation. Additionally, solar energy production does not pollute or emit fossil fuels, which means you can reduce your environmental impact by installing solar energy.

The type of renewable energy we interact with every day is wind. When you feel the wind, you are feeling the heat of the earth moving the air from one place to another. We can capture wind power by using large turbines, which rotate to generate electricity.

Although not always a viable option for every homeowner, wind power is becoming increasingly popular for utility-scale applications. Large wind farms covering several square miles can be found all over the world. Like solar power, wind power is clean and a growing and important renewable energy source supplying electricity to grids around the world. In 2017, wind farms produced more than six percent of the electricity used in the United States.

We can generate renewable energy from moving water just as we can from moving wind. Energy is generated when moving water passes through a turbine, spinning it to generate electricity. This usually occurs in large dams or waterfalls, where the water drops significantly in height. Two important hydroelectric (also known as hydroelectric) sites are Hoover Dam on the Colorado River and Niagara Falls on the New York border. York and Canada.

Many renewable energy sources have yet to make a significant impact on the overall US electricity mix, but hydropower is already a major player. Nationwide, large power plants accounted for 7.5% of the electricity used in the United States in 2017, and that number is growing. In addition to large-scale projects such as the Hoover Dam, hydropower can be generated by smaller projects, such as underwater turbines and low-level dams on small rivers and streams.

Hydropower is also a non-polluting energy source, as there are no emissions from power plants. However, hydropower has a greater environmental impact than other renewable sources, as it can alter water levels, currents, and the migration paths of fish and other freshwater life.

Renewable Energy Examples: Five Top Options Explained

There are immense sources of energy within the earth. The heat trapped when our planet was formed, combined with heat from radioactive decay in rocks deep beneath the crust, produced vast amounts of heat energy. Sometimes this heat is released in large quantities all at once, which we see on the Earth’s surface as volcanic eruptions.

We can capture and use geothermal energy by using steam from hot water to drive turbines. In geothermal systems, water is pumped underground. Once heated, it rises to the surface as steam and spins a turbine to generate electricity.

Additionally, geothermal heat can be used to provide heating or cooling to buildings. With this technology, known as a ground source heat pump, a fluid is pumped into the ground to heat or cool, where the temperature remains constant year-round at about 50 degrees.

Although still a small part of our energy mix, geothermal energy is an excellent renewable energy source, with great potential for energy supply. In Iceland, for example, geothermal energy already accounts for 90 percent of home heating needs and 25 percent of electricity. However, there are some concerns about geothermal energy, including the cost of building the power plant and its link to instability and earthquakes.

A final example of renewable energy is biomass. Biomass energy refers to energy obtained from recently living organisms such as plants or animals. Biomass is a renewable resource because plants can be grown quickly, and grow using renewable energy from the sun. Fuels such as ethanol and biodiesel (used in both cars and trucks) are also derived from biomass.

Biomass fuel is considered “carbon neutral”, meaning it does not add any additional carbon dioxide to the atmosphere. This is believed to be true because, in theory, as long as new plants are planted and each time they are harvested and burned for energy, those new plants will absorb the carbon produced by burning. , so no additional carbon is added. the environment . However, plant life takes time to grow, and to that extent biomass is very carbon neutral.

If you want to reduce your environmental footprint and save money in the process, you may want to look into solar energy. With the cost of solar dropping, now is the time to start generating solar energy.

On Energiesage’s Solar Marketplace, you can request quotes from high-quality, inspected solar installers near you. By comparing solar terms, you can be sure you’re getting the best solar deal. If you’re at the beginning of your solar purchase and want a ballpark estimate for installation, check out our solar calculator that can show you the upfront cost and long-term savings you can expect from your solar power system. According to the Environmental Protection Agency (EPA), Earth’s average temperature has risen 1.5 degrees Fahrenheit in the past century — and if we continue to burn fossil fuels, it’s projected to rise by 0.5, the next time that number is 8.6 degrees Fahrenheit. will increase. hundred years “

Human activities have released large amounts of carbon dioxide (CO2) into the atmosphere since the Industrial Revolution. Most greenhouse gases come from burning fossil fuels for production, and one of the first offenders is coal—a resource that is projected to last no more than another 250 years at current consumption rates.

So, not only are we raising the temperature of the planet’s general atmosphere, but we’re continually releasing resources in places like the Gibson Generating Station in southwest Indiana, which “put out more than 3,000 megawatts of power.” , 50 percent higher than Hoover Dam.” Tim Appenzler said.

Fortunately, promising developments in the renewable sector have created more opportunities for widespread change. For example, the city of San Francisco recently became the first city in the US to require solar panels on new buildings. The unanimous decision comes as part of the city of San Francisco’s goal to meet 100 percent of its electricity needs with renewables.

At the same time, the sun is not the only promising renewable resource for our planet; Wind and hydropower have also shown that it is possible to build large electricity networks. But some renewable resources are out of the ordinary – and in some cases, downright weird.
