Sometimes, renewable energy seems like magic and unattainable, the truth is quite different. Right from wind power to solar, biomass, hydroelectric, and geothermal sources of energy, we can transform our energy systems to renewable energy. Here are the benefits of using renewable energy sources.
Reduced global warming
For over two centuries, human activities have been overloading the atmosphere with poisonous gases such as carbon dioxide. These gases act as a blanket that traps heat within the lower atmosphere, resulting in a significant increase in global temperature levels. Global warming is associated with severe impacts on the environment including frequent storms, severe droughts, extinction, and rise in sea levels.
Fortunately, renewable energy emits minimal or no poisonous gases into the atmosphere. Even when the ‘life cycle’ emissions of renewable energy are considered, the global warming emissions associated with this form of energy is minimal. Life cycle emissions mean the emissions associated with all stages of technology’s life (manufacturing, installation, operation, and even decommission stages).
Enhanced public health
Water and air pollution associated with natural gas and coal plants is the major cause of respiratory issues, premature death, neurological damage, cancer, and a host of other health issues. And pollution affects everyone. A study done by Harvard University reveals that the public health and lifestyle costs associated with the effects of coal have hit $74.6 billion annually. That’s approximately 4.36 cents per KWh of the electric power produced and one-third of the average electricity bills for a typical household in the United States.
Besides, fossil fuels have a big impact on sources of water. For instance, both gas drilling and coal mining can pollute drinking water. All geothermal power plants and other manufacturing plants that are powered by oil, coal or gas emit thousands of cubic meters of poisonous gases to the atmosphere (air pollution) and use water for cooling (and ends up polluting water sources).
Various renewable energy sources have minimal levels of pollution, and if there is hope of breathing clean air and drinking clean water, we need to start using renewable energy.
Inexhaustible sources of energy
Heat from the earth, strong winds, fast-moving water, sunny skies, and abundant plant matter can offer a constantly replenished energy supply. Currently, a small fraction of United States’ energy comes from such sources. According to research, things are likely to change in the future as the energy experts argue that renewable energy can offer a reliable power in the future.
Job opportunities and other economic benefits
Fossil fuel technologies are mechanized and more capital intensive as compared to renewable energy industry which appears to be more labor intensive. Wind farms require maintenance technicians, and solar panels can’t be installed by machines. That means renewable energy can create more employment opportunities for each unit of electric power generated.
Renewable energy is a source of inexhaustible and probably increasingly competitive energy. This energy differs from fossil fuels in abundance, diversity, and potential for being used in any part of our planet.
