Facts About Renewable Energy

What is renewable energy?

The term renewable energy refers not only to an energy source but also to different alternative energy sources. In principle, it refers to the energy that can infinitely supplement its energy.

Unlike non-renewable energy sources, renewable energy sources can be regenerated or replenished indefinitely. In this article, you will learn more interesting facts about renewable energy.


What are renewable resources?

There are many types of renewable energy available. Among these energy types, you can use solar energy, wind energy, and geothermal energy to power your house. You will notice that some houses use solar panels to generate electricity and heat, while some houses use geothermal heat pumps for heating.

Using solar energy, you can get electricity or hot water to heat the house. Sunlight is converted into energy by photovoltaic panels: PV, the name for PhotoVoltaic-“Voltaic” comes from the Italian physicist Alessandro Volta (Alessandro Volta), the physicist because of certain inventions related to energy It is known as a method of generating electrical energy by converting solar radiation.

It is converted into direct current using semiconductors that produce a photovoltaic effect. Photovoltaic power generation uses solar panels composed of many cells containing photovoltaic materials.

However, the world’s future depends on the use of these renewable resources on a global scale to produce electricity and other forms of energy.

To achieve this goal, various renewable energy plants are now being built around the world. The largest of these are hydroelectric power stations, which are built near rivers and other places where water flows.

At the same time, wind power plants are becoming increasingly popular all over the world. Wind farms are under construction, and 20 or more wind power plants will be constructed to obtain maximum output from wind power plants.

Today, other forms of renewable energy are still used. Geothermal power plants are located in many parts of the world, while wave energy and tidal energy are concentrated on other countries’ ocean coasts.

Why use renewable energy?

Most things in life require energy to function. This energy can come from a variety of sources, some of which are renewable, and some are not. In recent years, there has been much discussion about renewable energy and its positive impact.

Benefits of renewable energy

The use of renewable energy is very cost-effective. Once companies or individuals have established a way to generate their own energy, they can bid farewell to utility bills. For example, solar energy is very useful for powering equipment in homes and generating heating systems.

If people use renewable energy, the world’s natural renewable resources will not be consumed quickly. Over time, natural gas, coal, and oil will all be consumed, which will cause them to cease to exist.

The supply of these naturally occurring substances is not unlimited, and eventually, they will be completely exhausted. Using green energy can prevent this from happening.

Using renewable energy helps keep the surrounding air fresh and clean. In contrast, using non-renewable forms of energy will produce smoke chemicals that will pollute the air. Fortunately, the use of renewable energy does not cause any pollution.

By producing renewable energy, no harmful and dangerous substances are produced. After all, the use of wind, water, or solar power generation does not involve any type of activity produced by-products. Unfortunately, the same cannot be said for nuclear energy, which is a tricky problem for some people.


Unlike non-renewable energy, renewable energy will eventually not be consumed. For example, those who use solar energy will always be able to use the sun’s energy. Wind turbines will always be able to use wind power. Tides will always produce enough waves to produce energy that can be easily utilized.

Another reason for focusing on alternative energy is that it helps slow global warming. By depleting the fuel that produces carbon emissions, the earth’s climate is changing, and it’s not getting better. This has led to the death of plants and animals in certain areas, and people are beginning to feel this effect.

Why use renewable energy ?

Most people would rather consider renewable energy than nuclear energy. This is due to a potentially harmful situation that a nuclear generator may cause. Chernobyl is a good example. Most people do not have to worry about nuclear energy and prefer to rely on renewable energy.

What are the types of renewable energy?

Most of the popular renewable energy sources include solar, wind, water and geothermal. Despite the increasing popularity of these sustainable energy sources, consumers are still figuring out and understanding how they generate electricity.

The technology and efficiency of generating energy from these energy sources are still lower than those most people are used to and have not yet reached the efficiency of fossil fuel production.

Cost efficiency has always been one of the biggest obstacles in the field of renewable energy. The technology behind these different types of renewable energy is much more expensive than the technology we currently use.

Geothermal energy system

The use of GHP in combination with traditional heating and cooling systems can reduce the energy consumption of these systems by 40% to 70% GHP compared to systems without geothermal energy. The upfront cost is several times that of the traditional system, and the investment recovery period is 2-10 years.

Wind Turbines

A machine that converts wind energy into electrical energy. The only fuel required is the wind, so it is free and unrestricted. Although the price of small home systems has become affordable, the initial capital cost may be considerable.

The theory behind a wind turbine is simple: a wind turbine drives the main shaft to run an alternator, which converts mechanical energy into electrical energy.

Then directly connect this power supply for consumption, storage, or both. Excess electricity can also be directed back to the grid for use by other users.

Essentially, uninterrupted continuous good wind energy supply throughout the year is rare. This is why wind turbines are often combined with another renewable energy source, solar energy.

Even if wind energy is used only as a supplement to the public power grid, it will be beneficial in cutting electricity bills and benefiting the environment.

Solar energy

The process of creating the above renewable resources is certainly much more expensive than our non-renewable resources. For example, compared to our current electricity supplier, converting solar energy to electricity is still very expensive.

Although our solar energy is free and renewable, installing solar panels that capture sunlight and convert it into electrical energy is very expensive.

Compared with fossil fuel power suppliers, even companies that currently use solar energy sell electricity at a higher price. In addition to all of this, in the long run, solar energy is still considered cheaper and more environmentally friendly.

No matter where you are, you can buy renewable energy from an electricity retailer to offset fossil fuels’ consumption. If you can’t afford the cost of switching to household alternative energy, its cost is only slightly higher than the standard energy price. It can provide you with a helpful environment, even if only a little.
