All About the Most Popular Sources of Green Energy

Green energy is energy that, when produced, causes little or no harmful impact on the environment and does not release harmful greenhouse gases into the atmosphere that causes global warming. So, green energy is basically environment-friendly energy. The other name of green energy is renewable energy. This article is about the several green energy options available to human beings as alternatives to fossil fuels.

Why do we need to increase our dependence on green energy?

The benefits of green energy are many. When the whole world is facing the consequences of global warming, green energy is our only savior. Green energy reduces the dependence of human beings on fossil fuels like coal, oil, and gas. It offers a wide range of economic and social benefits. The best part about it is that it is renewable, that is, can be replenished naturally.

Sources of green energy

We get green energy from natural sources like sunlight, rain, plants, wind, tides, geothermal heat and algae. All of these energy sources are inexhaustible. Earlier, people knew about the existence of only three green energy sources, namely, solar power, hydropower and wind power. Research into non-polluting green energy alternatives is progressing at a fast pace. So, several other sources of green energy are emerging.

These are the six most common sources of green energy:

  • Wind power

It is possible to utilize the moving air on the surface of the earth for pushing turbines. Stronger winds are more powerful and therefore, produce more energy.

  • Solar power

Solar power is one of the green energy sources. People use photovoltaic cells to capture sunlight that is turned into electricity. We can also use solar energy for heating water, as a natural light and for cooking food.

  • Hydropower

The water cycle of the earth generates hydroelectric power. This water cycle includes rainfall, evaporation, tides and also the force of the water that runs through a dam.

  • Biomass

We can convert biomass like wood waste, combustible agricultural remnants, and sawdust into energy. The reason is that biomass contains energy stored in it. It gets its energy from the rays of the sun.

  • Geothermal

Just beneath the crust of the earth, thermal energy is present in massive amounts. This energy originates from the formation of the earth as well as minerals’ radioactive decay. Humans have been geothermal energy in the form of natural hot springs for bathing for centuries. Now, we have also started using it for generating electricity.

  • Biofuels

Instead of burning biomass to produce energy, we can also transform these organic materials into fuel. Two most common examples of biofuel are biodiesel and ethanol.

This was all about the most popular sources of green energy that are inexhaustible and environment-friendly. Dependence on these forms of renewable energy is a must in order to reduce the rate at which the earth is warming up. Moreover, fossil fuels, being a finite resource, require millions of years for development and we have already consumed 90 percent of it. So, green energy is the last ray of hope.
