What is Renewable Energy?

Renewable energy, also popularly known as clean energy, comes from all the natural resources around us. Not only naturally but from processes that are constantly replenished around us. For instance, the sun always keeps shining, and winds keep on blowing. They may be available at different times, and weather conditions may be alternating, but they are constant throughout.

It’s also associated with green energy, which is recyclable and comes from natural resources. But in conclusion, all of these are safer and cause no harm to the surroundings.

People assume that this energy method is relatively new. Still, they don’t know that renewable energy and renewable energy sources have been here long. Many people have been using these to harness the power of nature and incorporate them into daily lives—for instance, heating, lighting, and even transportation. Over time, the wind has been used as a power source for boats to sail the sea and oceans. The sun has been a source of warmth for various kindle fires that can last into the evening. Eventually, people have switched to dirtier means over the past few decades, which have done nothing but harm our surroundings.

But with the knowledge and passage of time, the world is going back to cleaner ways to generate energy. Incorporating renewable sources is a way to capture and harness energy from a less harmful option and less expensive way. Retaining wind and solar energy are two popular renewable energy sources used by approximately 1/8th of the US.

The growth and development of renewable energy sources are at a larger scale today. It can be seen on various rooftops where people have installed solar panels to power their homes, even in rural areas where the electricity costs have been generally high. People have opted for renewable energy sources by using solar panels or wind farms for heating and lighting. So as the system becomes better, the critical goal  is to lessen the use of dirty fossil fuels and incorporate these ingenious methods of energy to make the future more secure, innovative, and better.

Different Types of Solar Energy

Solar Energy falls into five different categories that include

1. Photovoltaic System:

PV Systems are a commonly used method to generate solar energy. Solar cells produce electricity from the sunlight they get directly from the sun. These panels have 60 cells and can easily be adjusted at an angle that faces south, or they can mount it on a tracking device that tracks the sun’s rays and changes direction accordingly to grab the highest amount of sunlight over the day.

2. Thin Film Solar Cells

Thin Film Solar PV technology has enabled solar cells to get doubled in the form of rooftop shingles, building different facades, tiles on the roof, and even glazing skylights to absorb the maximum amount of sunlight.

3. Solar Water Heating System:

This energy involves warming water using the sun’s heat, an idea taken from nature where the sun quickly warms shallow waters. These are set on the roof from where different tubes carry the fluid and heat the water before it reaches the tap. How convenient and utilizing this system is!

4. Solar Power Plants:

These types of power plans are generally used to generate power for hundred thousand homes or more. Instead of fossil fuels, we can incorporate solar power for heating and boiling water, which further helps rotate turbines and activates the electricity-producing generator to power industries. This saves the cost of electricity and is pretty convenient for the atmosphere too. Save up on fossils and set up a solar power plant!

5. Passive Solar Heating:

Solar Energy can easily be harnessed from passive solar heating. This concept isn’t new, but people used it in ancient times. By using this system, we can incorporate sunlit flooring and walls that absorb the heat of the sun and release the heat during the night to keep houses and buildings warm. This can be ideal for places where it is cold and snowy during the winters and can help cut down heating costs and disasters.

Hydroelectric Power

From windmills to turbines that are as tall as skyscrapers, we have come a long way. Wind energy is an efficient way through which the blades of these turbines feed energy into an electrical generator that further aids in the processing and production of electricity.

Wind Energy is considered one of the cheapest ways of acquiring energy and is utilized in quite a few places all over the globe, such as in different states of the United States, including California, Texas. It is also used by China, Germany, and the United Kingdom. Places ideal for wind turbines are anywhere with high wind speeds; it could be hilltops and open plains or areas offshore in the open water.

Geothermal Energy

Geothermal Energy

Have you ever relaxed in a hot spring? Well, that’s news because you have utilized geothermal energy? It may have been a calming experience but know that there is more to it than just relaxation. We are all aware that the Earth’s core is similar to the sun’s surface in terms of heat. So, when we dig deeper wells, it brings out boiling underground water towards the surface as a hydrothermal source. This water is then pumped to various turbines nearby to create electricity.

Did you know that comparatively, the emissions of a geothermal plant are pretty low if the water and the steam that is pumped goes back into the reservoir? How convenient! Be sure to dig up areas that aren’t too hot but hot enough to function the turbine.

Biomass Energy

Various Sources of Biomass Energy

Biomass energy is obtained from biomass which is the organic material that comes from both animals and plants. When this biomass is burned, the energy released in heat is again utilized to generate electricity from a steam turbine.

This renewable energy source can be used in farms and areas with many animals because then it will be cheaper to maintain and pretty easy to power the nearby locations.

Tidal and Wave Energy

Tidal Energy created in the Oceans

This energy that is obtained from the ocean is still in its development phase. The gravity of the moon rules the sea, and that makes this energy a pretty attractive option. Tidal and wave power primarily rely on structures similar to dams. Anchored devices on the surface of the ocean are used to generate this energy.
