In the United States, Renewable Energy is the fastest-growing source of energy. It is responsible for around 6 percent of all electricity generation, making it the cheapest energy source in many regions. California, Texas, Oklahoma, Kansas and other states are among the top wind-power producing regions. Wind turbines can be placed wherever there is a high wind speed or offshore in open waters. Another renewable energy source, hydropower, harnesses the power of fast-moving water to generate electricity.
Wind energy is a renewable source of energy that does not pollute the environment. Unlike coal, wind energy does not release carbon dioxide or other harmful products into the air, compromising the quality of air and water. Investment in wind turbine technology can also create new jobs, as wind turbines on farms require maintenance. And unlike conventional sources of energy, wind energy can be used in both industrial and residential settings. A large-scale wind farm can generate enough energy for an entire city.
Companies have also begun investing in renewable energy technologies. The Iberdrola group, for example, began investing in renewable energy more than two decades ago. By the end of 2021, the group had 38 GW of installed renewable energy capacity worldwide. The company is at the forefront of the energy transition, and has extended its investment plan to 2030. It aims to double its renewable energy capacity by 2030, which is well within reach. And with a steady increase in demand, renewable energy costs have decreased considerably.
Another advantage of renewable energy is that it is not finite like fossil fuels. As time goes by, renewable energy will replace fossil fuels and have a low environmental impact. Traditional energy sources are finite and contribute to global climate change, while renewable energy will not cause any emissions and will replenish itself continuously. They are therefore the perfect alternative energy sources. It is also the only source of energy that does not contribute to global warming. It is the future of energy.
Solar energy and wind power have many uses for our homes and businesses. They can power buildings, electricity generation, and transportation. They are even used to produce ethanol and biodiesel. Renewable energy sources are considered to be zero, low, or neutral in greenhouse gas emissions. Their emissions are neutral because they have absorbed carbon dioxide during the growing process. The overall environmental impact of renewable energy depends on its life cycle. They also create hydrogen, which is used in fuel cells for vehicles.
In developing countries, the development of Renewable Energy has accelerated dramatically. In fact, many parts of the world have made the transition from fossil fuels to renewable sources. The development of hydroelectric dams is a prime example of renewable energy. Even today, hydroelectric dams are popular in developing countries and are used to produce hydroelectric power. In China, the Three Gorges Dam and the Itaipu Dam are the world’s largest hydroelectric power facilities.
Developing renewable energy requires political will and public support. The Renewable Fuel Standard requires utilities to purchase renewable technologies in order to meet their requirements. Under the original Renewable Fuel Standard, this volume was limited to 2.78 percent of gasoline. Under the Energy Independence and Security Act, the Renewable Fuel Standard was raised to 36 billion gallons by 2022 – about 7 percent of total gasoline consumption. This is an impressive step forward. The public’s backing for Renewable Energy is increasing steadily.
The world’s renewable energy sector is thriving. Renewable energy is estimated to provide around twenty-eight percent of all electricity in the first quarter of 2020. By comparison, coal and natural gas are responsible for about 60% of the world’s electricity supply. Since renewable energy is growing in importance, it is becoming essential to update the electricity grid. There are many challenges that need to be overcome before the global market can become sustainable. These challenges have made Sustainable Energy a buzzword.
Solar energy is one of the most popular sources of renewable energy. Its massive resources can be harnessed anywhere on Earth where sunlight is available. Solar radiation (also known as insolation) depends on geographic location and weather conditions. Solar photovoltaics will add around 139 GW of global electricity capacity by 2020. Solar energy will also contribute to the reduction of carbon dioxide emissions from the atmosphere. A key challenge for solar energy is that it cannot be used without efficient batteries.
Burning fossil fuels releases sulfur dioxide into the air. Sulfur dioxide impairs breathing, weakens pulmonary defenses and aggravates cardiovascular disease. Additionally, 25 percent of the world’s nitrogen oxides react with sunlight to produce smog and ground-level ozone, both of which are harmful to human health. Furthermore, smog also lowers the immune system’s ability to fight infectious diseases. It is vital to switch to renewable energy to combat these health issues and protect the environment.
