The 5 Main Types of Renewable Energy and the Problems They Face


Written by:

Renewable energy sources are being used more and more by people and companies around the world. Unfortunately, it is not making enough of a change yet. Some alternative energy sources are still being developed so we can use it more easily and others are a bit too expensive for everyone to install. If you can find a way to use these energies at home, do so.

There are 5 main types of renewable energy:

1. Wind power

Currently, this is the cheapest form of renewable energy. It uses the wind to power turbines that generate energy. There are no pollutants that are produced through this process. There are some concerns about the turbines and how they will affect the landscape and the habitat in years to come.

2. Solar power

As long as the sun shines, solar power will be a renewable energy source and we will have power. Solar panels are used to turn sunlight into energy without any negative pollutants as a result. The drawbacks of this type of energy are the cost of the solar panels and the amount of energy that is generated on days that are overcast.

3. Biomass

This type of renewable energy uses plant matter and animal waste to generate electricity. If these products are converted properly, it produces very little pollution and is a low-carbon energy source. This is a trickier renewable source and there is still some development needed. The conversion process is costly and if it is done incorrectly, it can cause damage to the environment.

4. Geothermal energy

This type of energy is generated through heated water and steam from the Earth. The steam is turned into electricity with no pollutants as a result. There are several geothermal power stations in California that produce 5% of the state’s power needs. The problem with this type of energy lies in the cost of building the plants and the availability of geothermally active areas.

5. Hydroelectric power

This type of power uses water running or flowing over turbines to make them move and produce electricity. Hydropower currently provides 20% of the world’s energy needs. Costs and potential disruption of wildlife, land, and communities are problems that we face with this type pf power.

As you can see, there are still a lot of development and research to be done to make these energy sources more readily available. Until then, try and do what you can to conserve energy.
