If you want to know the different renewable energy sources, you have come to the right place. But before moving ahead, it is vital to understand what it is exactly? And how using it is beneficial for our planet and economy. In this article, we are going to cover up all these topics.

What is renewable energy

Renewable energy is the type of energy that comes from natural sources and constantly recharging processes. Moreover, it is a source of low-cost clean energy. For example, sunlight and wind are the best sources of renewable energy.

However, renewable energy is the new technology of utilizing nature’s power. For a long time, this energy has been used in lighting, transportation and many more. For example, the sun provides warmth and helps to create power for various purposes, and wind energy helps to power up the boats to sail and windmills to grind grains. Over the decades, many people are moving towards cheaper electricity sources such as coal and cow dung.

Nowadays, people are becoming more innovative and have low-cost ways to retain solar and wind energy. Moreover, renewable sources are becoming vital energy sources for most of the people around the world. Solar panels on the rooftops of many homes also help sell power back to the giant offshore wind farms. However, many rural areas depend on renewable energy for lighting and heating.

Simply, renewable sources are continuing to integrate across the region and create a smart and secure electricity grid. Now let’s start with understanding different types of renewable sources.

Different types of renewable energy

Below is the list of different renewable sources with detailed information;

1. Solar energy

Over a decade, humans are utilizing solar energy to grow crops, dry foods and stay warm. Nowadays, the sunlight falling on the earth is harnessed in many ways, such as power devices, warm water, and heat homes and companies.

We can install solar panels on our rooftop to generate solar energy. The cells present in the solar panels made of silicon are expensive and convert the warmth of sunlight into power. However, the solar system mostly generates electricity for homes, businesses and many community projects. It can generate electricity for thousands of homes using panels that concentrate sunlight on many solar cells. Moreover, floating solar farms can be beneficial for using non-sensitive ecological wastewater bodies.

We can generate solar energy to power up the whole house at a smaller scale, but we can produce more than enough electricity through passive solar home design. It is a design of having south-facing windows through which sunlight enters and stores heat in bricks, tiles and concrete.

Lastly, it does not produce any greenhouse gases and air pollutants. That results in no harmful impact on the environment.

2. Wind energy

Now we are moving forward from the old-fashioned windmills to the tall turbines. These tall turbines are the best ways to generate power. When the wind moves the blades of the turbines that start feeding the electric generator to generate electricity, it works.

However, wind energy is becoming popular in many parts of the countries involving Oklahoma, California, Texas and Kansas. We can place turbines on high wind speed areas such as open plains, hilltops and offshore in open water to generate electricity.

Small cell phone companies, boats, and ranchers use small turbines to generate energy. Moreover, a wind turbine reduces your electricity bills depending on power needs and wind speed.

3. Hydroelectric energy

Though before wind energy, wind energy was the largest source of electricity in the world. Hydropower works with fast-moving water in a large river from a high point. The force of water spins a generator’s turbine blade, thus converting water’s power into electricity.

But large hydropower plants and mega-dams are considered to be non- renewable sources of energy. Hydroelectric plants tend to decrease the natural flow, thus, harming the living water bodies. Therefore, small hydroelectric plants are a little better because they do not harm the environment and restrict only fraction flow.

4. Biomass energy

Biomass is an organic material, including crops, plants, animals, trees and waste wood. When a biomass material is burned, that converts heat energy into electricity with a steam turbine.

For generating electricity, biomass particles are the best alternatives to fossil fuels and coals. But recent studies show that the forest biomass material produces higher carbon emission than fossil fuels.

Whereas, there are some of the biomass materials that produce low carbon emission under the right situations. Chips from sawmills quickly decompose and produce less carbon dioxide.

5. Geothermal energy

Geothermal energy is another best way to produce electricity from the core of the earth. The slow decay of radioactive material at the center of the earth results, making the center warm like the sun’s surface.

We drill deep and bring out hot water from the earth’s core to the surface, pumped through a turbine to generate electricity. Geothermal plants have low carbon emission because they can use the pumped steam and water into the reservoir to generate electricity. There are many ways to create geothermal plants in the areas where underground ponds are not present, but it seems that it increases the risk of earthquakes in the areas considered hotspots for earthquakes.

Nowadays, geothermal technology is trending worldwide. For example, the coils at the back of your refrigerator are the type of mini geothermal heat pump that removes heat from inside to keep food cool and fresh. We all can use geothermal pumps to warm our house in winter and to cool our homes in summer.

The geothermal system is expensive to install, but it is a one-time investment only because they last longer than air conditioners and have low maintenance issues.

6. Tidal energy

The moon controls our ocean that makes tidal energy possible. This system is still under process, but some tidal energy plants like dams that are harmful to wildlife. However, wave energy depends on the dam-like structure or ocean floor over the water surface.

So these are the different types of renewable sources of energy that are trending nowadays worldwide. These sources of energy are beneficial for our environment and bring a better future.

What are non- renewable sources

Coals and fossil fuels are known as the non-renewable sources of energy because they release carbon dioxide in our atmosphere, thus resulting in global warming.

However, burning wood is better than coal burning. But burning wood is not the best choice because it releases some harmful particles in our environment, resulting in the reduction of natural habitat and deforestation.

Why Renewable Energy Is Important

Using renewable energy is one of the best ways to reduce the harmful effect on the environment. Clean energy and greenhouse gases are the number one electricity source because it decreases the smog and chemicals in the air.

However, it takes up a lot of time, money and consistent support from both state and federal mandates to replace fossil fuel infrastructure with renewable energy plants.

There are benefits to people, businesses and the planet through renewable sources of energy.

All energy sources have some harmful effects on our environment, unlike human activities. However, each renewable energy has its benefits. But the benefits of renewable sources over the impacts of non-renewable sources are unbelievable.
