Renewable energy offers a host of benefits to individuals, businesses, communities and countries. It reduces reliance on fossil fuels, improves resilience and security of energy supply, and cuts greenhouse gas emissions.
Solar panels, wind turbines, hydropower dams, biomass and geothermal power are all examples of renewable energy sources that generate electricity. These renewable energy resources are natural, clean and sustainable, and provide a source of low- to zero-emissions energy.
However, these sources do not always operate continuously. For example, solar and wind energy need battery storage to generate energy when the sun is not shining or the winds are not blowing.
In addition, the generation of some forms of renewable energy can cause environmental harm. Critics of corn-based ethanol, for instance, point out that it competes with food markets and supports the same harmful agricultural practices that contribute to toxic algae blooms in waterways. And the operation of wind turbines can kill birds and bats that get struck by the spinning blades.
The good news is that the use of renewable energy can help offset these negatives by generating many high-quality jobs in manufacturing and installation. These jobs tend to pay above average wages, and are helping to drive economic growth. This growing sector also helps reduce energy costs, making it easier for consumers to transition to clean electricity.
