Renewable energy can be through various methods such as wind, solar, hydroelectric, and biomass. Most methods of generating renewable energy are solar, wind, and hydro.
Renewable energy is clean, affordable, and will never run out. The main idea behind this alternative energy is that it’s infinite! It’s something everyone can benefit from, which is why it’s significant to know the different forms of renewable energy.
Here are some of the most common forms of renewable energy.
Wind power is one of the fastest-growing forms of alternative energy. Even though it is a widely used form of generating renewable energy, wind power still contributes to less than three percent of the world’s total energy. However, the growth rate is high, and last 2020 wind power contributed 10% of global electricity needs.
Windmills are typically used to generate wind power, but there are other methods. It’s estimated that 11 states in the U.S. have the potential to generate enough wind power to fulfill all of our nation’s electricity needs.
Solar power is the second-fastest-growing form of renewable energy and contributed 16% last 2020! This power is through the photovoltaic cells, which change sunlight into electricity. A solar panel can either be stationary or move in the direction of the sun throughout the day.
If you’re looking to go off the grid, this is a good option for you! Solar power is one of the cheapest and easiest forms of renewable energy available.
Biofuels and Bioenergy
The energy that is derived from organic sources such as plants and animal waste is called bioenergy. This form of energy can be used for electricity generation, transportation and cooking. You may not know but biofuel is the third well-known source of renewable energy after wind and solar! Biofuels contributed 14% to global energy last 2020.
Hydroelectric energy is created through the movement of water. This form can produce electricity, potable water, and irrigation which are all great advantages! It truly is a gem of a form of renewable energy!
Geothermal energy is broadly used for heating and generating electricity. This form of renewable energy is widely available, but not widely distributed. It is because it costs a lot of money and labor to create the infrastructure needed for geothermal energy. However, there are countries like Iceland and El Salvador that use this form of renewable energy as their main source!
Ocean energy is another form of renewable energy that is not widespread due to the high costs needed for installation. This form of alternative energy includes tides, waves, and thermal differences in ocean water. The technology used to harness this power can be very expensive, but it’s worth it! Countries like India are investing in this type of renewable energy.
Other Forms of Renewable Energy
There are other forms of renewable energy that you may not have heard about! For example, solar updrafts are a way to generate electricity using the buoyant force from warm air. Another form of power generation called tidal stream uses turbines inside underwater tunnels created by tides! These methods allow us to harness the power of the ocean.
There you have it! Now you know all about the different forms of renewable energy and how they contribute to global energy needs. Renewable energy is the future, and we should all do our part in contributing to its growth.
