Using the Earth’s internal heat to create electricity is the basis of geothermal energy, a renewable energy source. Geothermal power plants are used to extract heat from the Earth’s crust and convert it into electricity. Geothermal energy is a clean and reliable source of energy that can be used to supplement other renewable energy sources. Some of the advantages of geothermal energy include:
- There are no emissions of greenhouse gases from the use of geothermal energy.
- Geothermal power plants have a small land footprint, making them an ideal energy source for areas with limited land resources.
- Geothermal energy is a reliable source of baseload power for communities.
Biomass energy is a green energy powerhouse that harnesses the power of organic matter, like wood, crops, and waste, to produce electricity. Whether burned directly or converted into biogas or biofuels, biomass energy is a versatile and reliable energy source that can complement other renewables. The perks of biomass energy are impressive:
- A renewable energy source that doesn’t add to greenhouse gas emissions, biomass energy, is a clean and green solution to power our lives.
- Biomass can be locally sourced, reducing our reliance on energy from afar and boosting local economies.
- Biomass energy can work alongside other renewables to provide baseload power to communities to ensure a steady supply of electricity day and night.
One of the challenges of renewable energy sources is their intermittency. Solar panels and wind turbines produce energy only when the sun or wind shines. Batteries and pumped hydro storage are two examples of energy storage technologies that can be used to reliably store and later use the excess energy produced by renewable energy sources. Energy storage technologies can also help to balance the supply and demand of electricity, making the grid more stable and reliable.
The Future of Renewable Energy
Renewable energy solutions can potentially transform how we generate and consume energy. In the past few years, renewable energy prices have decreased significantly, making it cheaper than traditional electricity. Both governments and corporations are investing in renewable energy solutions as a means of lowering their carbon footprints and achieving their environmental objectives. The International Energy Agency predicts that renewable energy sources will account for 90% of the increase in global electricity generation between 2019 and 2025.
