Renewable Energy

Before the mid-19th century, almost all of the energy available to man was renewable. The oldest known use of renewable energy is burning biomass for fuel, but this technique only became widespread hundreds of thousands of years ago. Harnessing wind power for ships dates back at least 7000 years, to the Persian Gulf and the Nile. Even earlier, geothermal energy was harnessed for bathing, cooking and space heating. In fact, it is now the most widely used source of energy for humans today.

The use of renewable energy is increasingly becoming a necessity as the Earth’s nonrenewable resources deplete. Not only will this method help us sustain our growing population, it will also help to keep our planet healthy for future generations. However, renewable energy does have some challenges. For example, it is variable and may not be the best solution for every situation. It also requires the use of power storage, as well as other sources of base load. Renewable energy also tends to take up thousands of hectares of land. Lastly, renewable power plants can lead to environmental concerns and even opposition from local residents.

It is important for energy leaders to use appropriate terms when discussing renewable energy. In the U.S., 82% of the population support renewable energy, and this support is consistent across demographics. Renewables are bipartisan; Republicans are more interested in the economic benefits of renewables while Democrats are more concerned with climate change. To successfully engage the public, renewable energy should use appropriate terms. If it isn’t, the energy industry will never succeed.

Businesses that have a sustainability goal often drive renewable energy development. They may build their own renewable energy facilities or purchase certificates. These businesses are largely responsible for the growth of renewable energy in the U.S., while some cities are committed to using 100% renewable energy. Moreover, government incentives such as carbon pricing, renewable portfolio standards, and fuel economy requirements encourage renewable energy development. Many companies have purchased record amounts of renewable energy in 2018.

Biomass is an example of renewable energy. It is a form of fuel derived from plant and animal sources. This fuel is a more efficient and cleaner way to produce electricity. Using biomass for energy production is also cheaper than fossil fuels, which are not infinite. And, unlike fossil fuels, biofuels are sustainable, as they can be grown in a continuous cycle. They also use biomass and produce biodiesel, an alternative fuel to conventional diesel.

Biofuels are another type of renewable energy that has a negative side. While the production of biofuel is more environmentally friendly than fossil fuels, it does require natural resources, which is why biofuels require forests. Furthermore, biofuels create carbon emissions, which can affect climate. But biofuels also provide us with food, and this is a win-win for everyone! But, it can be difficult to make the transition to sustainable energy.

Wind turbines produce electricity by turning turbines. The wind pushes these blades, which generates mechanical energy. This mechanical energy can be used in households or stored in power grids. Solar energy can be harnessed with photovoltaic cells. These cells can be used to power computers and calculators. Solar panels can even be combined to create solar arrays and generate even more electricity. These sources are a viable alternative for electricity production, but the windmills do have a few negative sides as well.

However, the U.S. energy consumption of renewables will still only be about five percent by 2020. However, this will increase steadily as innovation brings down costs and renewable power begins to deliver the clean energy we are looking for. In the United States, solar and wind generation are breaking records and are being integrated into the national electricity grid without compromising reliability. The future of renewable energy is bright! It is the only way we can ensure a sustainable future for our planet.

Hydroelectric plants are also an option for electricity production. However, they are limited by geography, and mega-dams often restrict the flow of a river. In addition, geothermal energy requires large quantities of fresh water for steam generation, which is problematic in areas with little or no fresh water. Other renewable energy sources include biomass, which is made from organic matter that has recently lived. Photosynthesis produces energy in plants, and the energy in those tissues is stored in the plant after death. Biomass fuels include crops and manure.

Hydropower is the most ancient and most reliable source of renewable energy. Hydroelectricity is used in almost every U.S. state. Hydroelectric power plants convert the flow of rivers and streams into mechanical energy to turn turbines. Solar energy, on the other hand, requires a large surface area and constant sunlight. Solar farms should be coupled with energy storage solutions. They can provide electricity and heat, as well as generating heat. If properly combined with renewable energy storage solutions, solar power is an excellent choice for a green future.
