It is scientifically proven that burning of fossil fuel is the main cause of climate change. Though, there are several other factors that are also contributing towards the climate change but fossil fuels do substantially more damage. According to the U.S. Energy Information Administration, about 67 percent of the electricity generated was from fossil fuels in the past years. It dumped millions of tons of carbon dioxide in the atmosphere, a most known greenhouse gas. The burning of the fossil fuels is considered as the major factor for climate change as it involves the emission of the greenhouse gases. These gases trap the sun’s radiation which would reflect back otherwise, causing rise in the earth’s atmospheric temperature.
Renewable energy is considered as the most effective tool to fight climate change. There are several pertinent reasons to believe it will succeed. Renewable energy sources include biofuels, biomass, geothermal, hydropower, solar and wind. They offer minimal effects on the environment, minuscule effects on global warming and negligible effects on air quality. Past few years have experienced remarkable growth in the production and use of Wind and solar energy. As it is considered as green fuel, it is becoming increasingly competitive with fossil fuels. Furthermore, new renewable energy is already cheaper than continuing to operate old, inefficient and dirty fossil fuel-fired or nuclear power plants.
The cost of generating electricity from wind and solar is also declining and its growth is widely expected to accelerate over the next several years. It is also believed that capacity to generate green energy will going to get increased manifolds by 2021. With careful planning, renewable energy options like increased energy efficiency and storing energy for use later will help pave the way.
The benefits are huge
The benefits associated with the renewable energy are huge. Apart from the climate benefits, renewables also provide a wide range of market and public health benefits. Not only, renewable is environmental friendly, but also it is cost-effective. One of the published report suggested that renewables have supported nearly 200,000 jobs, provided $5.2 billion worth of health benefits through improved air quality, and also resulted in global climate benefits of $2.2 billion. If we talk of recent developments, then by 2030, California is proposing to reach 60% renewable energy in order to put check on carbon emission. America’s most oil-dependent state, Hawaii has pledged to be 100% renewable by the middle of the century.
However, 100 percent Renewable is tough to achieve
Considering that goal of 100% renewable energy, seems deceptively easy to curb climate change. The picture, however, is not as clear as it appears to be as renewables account for less than 8% of the world’s total power output. So, much is indeed required to put a check on the climate change. To follow a middle path, however, is a good approach in which the world just not only moves towards the clean energy but also take steps to prevent net emissions of greenhouse gases.
