What Are The Different Types Of Energy Resources – Technologies such as solar and wind power are common around the world and both are examples of renewable energy sources. There are several ways to obtain energy from renewable sources. These alternatives to fossil fuels will become an increasingly important part of our energy mix in the coming years.
Renewable energy sources are energy sources that are continuously replenished as a result of natural processes. These sources are often referred to as alternative energy or renewable energy because they are a fuel option that can replace traditional non-renewable fossil fuels. Fossil fuels such as oil and coal produce energy when burned, but their supply is limited because they are not naturally replenished in sufficiently short intervals to be used by humans.
What Are The Different Types Of Energy Resources
Renewable energy sources are beneficial because they have a very limited negative impact on the environment compared to fossil fuels. Previously, they were too expensive for general use. However, that is changing – many renewables are cost-effective and some can even be a smart financial decision for homeowners, businesses and governments. Solar power, in particular, is a great option for property owners looking to reduce their environmental footprint while saving money.

There are five main technologies that are considered “renewable energy”. We’ve put together an infographic below to compare the top five renewable energy options side by side:
One of the most popular types of renewable energy is solar energy. Solar energy comes from the sun, which provides the entire planet with the energy it needs to survive. Using solar panels, we can harvest energy directly from sunlight and convert it into electricity that powers our homes and businesses. Solar energy can also be used to generate hot water or charge battery systems.
Solar energy benefits both your bank account and the environment. The cost of solar energy continues to drop, and installing solar energy in your home will almost always save you money over the lifetime of the installation. In addition, solar power generation does not pollute or emit fossil fuels, which means you can greatly reduce your environmental impact by installing solar power.
Another type of renewable energy that we encounter every day is wind. When you feel the wind, you just feel the air moving from place to place due to the uneven heating of the Earth’s surface. We can harness the power of the wind by using powerful turbines that generate electricity as they spin.

While not always a practical option for the individual homeowner, wind power is becoming increasingly popular for industrial-scale applications. Giant wind farms spanning many square miles can be seen all over the world. Like solar power, wind power is largely non-polluting and is a growing and important renewable energy source that powers power 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 as well as from moving air. Power is generated when water flows through a turbine and is rotated to generate electricity. This is often the case with large dams or waterfalls where the water drops significantly. Two important places where hydropower (also called hydropower) is generated are Hoover Dam on the Colorado River and Niagara Falls on the border of New York and Canada.
Most renewables have not had a significant impact on total US electricity, but hydro power is already a major player. In 2017, 7.5 percent of the electricity used in the U.S. came from large hydroelectric plants across the country, and that number is growing. In addition to large projects such as the Hoover Dam, hydropower can be produced by smaller projects such as underwater turbines and lower dams on small rivers and streams.
Hydropower is also a non-polluting source of energy, as hydropower plants do not produce any waste. However, hydropower has a greater environmental impact than other renewable energy sources because it can alter water levels, currents and migration routes for fish and other freshwater organisms.
Major Types Of Renewable Energy Resources
The earth has a great source of energy. The heat trapped during our planet’s formation, combined with the heat generated by radioactive decay in rocks beneath the earth’s crust, produces large amounts of geothermal heat energy. Sometimes this heat is released in large amounts at once, which we see on the surface as volcanic eruptions.
We can capture and harness geothermal energy by using steam from heated water to spin a turbine. In a geothermal spring system, water is pumped underground. When heated, it rises to the surface again as steam and spins a turbine to generate electricity.
In addition, geothermal heat can be used directly to heat or cool buildings. With this technology, known as a ground source heat pump, liquid is pumped from underground for heating or cooling, where the temperature remains constant at around 50 degrees all year round.
While geothermal energy is still a small part of our energy mix, it is a promising renewable energy source with huge potential for energy supply. In Iceland, for example, geothermal energy already meets 90 percent of home heating and 25 percent of electricity. However, there are some concerns about geothermal energy, including the cost of building the plant and its relationship to surface instability and earthquakes.

One of the latest examples of renewable energy is biomass. Biomass energy is any energy produced from recently living organic matter such as plants or animals. Biomass is a renewable resource because plants can be grown relatively quickly and their growth uses renewable solar energy. Fuels such as ethanol and biodiesel (both used in cars and trucks) are also derived from biomass.
Biomass fuels are also considered “carbon neutral”, meaning they don’t add extra carbon dioxide to the atmosphere. This is assumed to be true because basically, when new plants are planted and grown, when plants are harvested and burned for energy, these new plants absorb the carbon produced by combustion and release it into the atmosphere. . . However, it takes time for the plants to grow back, and there is some debate about the extent to which biomass fuels are truly carbon neutral.
If you want to reduce your environmental impact and save money in the process, you may want to consider switching to solar power. As solar energy prices continue to fall, it’s time to start generating solar energy.
