5 Sources of Alternative Energy
All people need oil and electricity to run cars, electronic devices, heat water, etc. The energy consumption is growing every year. The US energy information administration projects the 28% increase in world energy use by 2040.
Therefore, humanity in seeking alternative resources of energy that will provide enough power to boost technical progress. Let's take a closer look at the most popular sources of alternative energy in this post.
1. Water Power
It is the most widespread way to produce electricity with minimal impact on the environment. We all know the Hoover Dam in the Black Canyon. For more than 89 years, it generates electric power with no interruptions. Moreover, it provides enough water for people, which is also a valuable resource. However, it has one disadvantage. Since a dam stops water, it requires large territories for flooding.
In case you're a student and need to write a research paper about the impact of dams on the environment but don't want to hassle with this, feel free to order an essay service writing online.
2. Wind Energy
Wind energy is the second widely used green energy in the world. It works simple, a wind turbine rotates and produces electricity. It is a high-efficiency way to produce electric power. One wind turbine can provide 1.5-3 MW of electricity a day. Mere words, it's more than enough to supply more than 1500 average households in the US.
Unluckily they require strong wind to work on high efficiency all the time. Therefore, people install them at plains and oceans to obtain maximum profit from the surface and weather conditions.
However, if you decide to power your house with a wind turbine, you need to take into account the fact that when the weather becomes calm, you will have an electricity outage. In consequence, it will be hard to run a desktop and find an answer to the question, "Who can do my math homework for me?" on the Internet without electricity.
3. Solar Plants
Solar energy is one of the most fast-growing and effective ways to replace fossil energy. A large solar panels plant can produce enough electricity to power a university's campus or a small city by daylight.
For instance, Princeton University has a large solar power plant that provides enough energy to charge 10,000 laptops at the same time. The solar power plant at Rutgers University brings enough power to cover 10% of electricity consumption and provides shadow for cars on its parking. Above that, Arizona Western College covers 100% of its daylight need for electricity using solar plants.
4. Hydrogen Energy
It is one of the most forward-looking alternative energies. It has a high potential and low price. Moreover, it has zero emissions. Hydrogen and oxygen atoms combine into hydrogen engine cells and produce electricity, water, and some heat.
If you need to write a research paper about the fuel for future cars but have no ideas, feel free to find some help online. Open a browser and specify the following question, "Who can do my college homework for me?" in a search bar to find a reliable paper writing service.
5. Geothermal Power
The use of geothermal power isn't widespread worldwide because it requires a particular territory where magma comes close to the Earth's surface. People use the heat of magma to heat water and produce electricity by using a steam engine.
Unfortunately, fossil energy sources are not limitless on Earth. Don't be afraid of changes and support renewable energy to save our planet despite the continuous growth of technology and population.
