The energy produced from fossil fuels, such as coal and natural gas, releases a huge amount of carbon dioxide and other greenhouse gases. These gases contribute to global warming and local air pollution, which affects health. Reducing emissions and shifting towards renewable sources is vital to halting climate change. It also helps address air pollution and improve health.
The cost of renewable energy sources is falling rapidly, and as a result, many people are shifting to these clean energy sources. These technologies are vital to tackling the climate crisis and have numerous benefits.
But it’s also important to recognize that not all fossil fuels can be replaced with renewables. In fact, despite a massive drop in costs, renewable energy developers still mention that renewables have not been replacing fossil fuels at the rate you’d expect. This is because the investments, policies, and infrastructure of the energy industry are highly skewed in favor of fossil fuels.
Renewable energy is derived from natural sources and processes that are constantly replenished. This includes solar, wind, wave, and geothermal power. People have been harnessing these resources for transport, heating, and lighting for thousands of years. Today, renewables are gaining in popularity because of concerns about global warming and air pollution. However, renewables also have their disadvantages. These include cost, environmental impact, and geographic limitations.
It’s More Efficient
When electricity is produced from renewable sources, it displaces fossil fuel-fired generators. This reduces carbon emissions and lowers energy costs. This is why many countries are pursuing policies supporting renewables, including priority dispatch for them and special feed-in tariffs. Some 50 countries have these provisions in place. Another benefit of using renewables is that they are generally cleaner. For example, wind turbines and solar panels are much less likely to release toxic substances into the air or water than coal-fired generators. The other key advantage of renewables is that they are generally easier to access than other energy resources. They can be used for small-scale on-site generation rather than in large centralized plants.
It’s Better for the Environment
Burning fossil fuels – coal, oil and natural gas – to generate energy releases harmful greenhouse gases that cause climate change. Transitioning to renewable energy is one of the best ways to fight climate change. Renewable sources like wind, solar and hydroelectric produce electricity with far lower emissions than those produced by burning fossil fuels. These sources also emit fewer air pollutants, contributing to poor health and indoor air quality. Moreover, they’re more reliable power supplies. They reduce the risk of fuel spills and lessen the need for imported fuels. This increases energy security and helps protect our nation’s natural resources.
