Steve Proehl/Image Bank/Getty ImagesBecause people's homes were connected to the grid, their choices were limited to the source of energy used to generate electricity. This usually involves polluting fossil fuels such as coal or natural gas.
But in the year 2022 will see a major shift in power generation in the United States, according to the US Energy Information Administration, where for the first time as much electricity will come from coal as from wind or hydroelectric power. The EIA predicts that renewable energy will eventually overtake natural gas as the primary source of electricity in the United States.
Another major energy revolution is taking place in the United States as solar power plants, which take photos from the sun and convert them into electricity, have become cheaper and more efficient. The EIA's average cost of solar panels has fallen from $1.96 per kilowatt peak in 2010 to 34 cents per kilowatt peak in 2021.
It is clear that solar energy has taken off in the United States and will continue to grow in the coming years, especially as more people benefit from the federal government's renewable energy tax credit.
But what exactly is renewable energy and why is it important?

Traditional energy sources such as coal or natural gas are taken from the planet and converted into fuel to generate energy. These high carbon materials are limited and will eventually run out. Extraction and burning of these fossil fuels for energy release such as carbon dioxide and methane and another major source of pollution is the main cause of global warming .
Renewable sources, on the other hand, generate energy from sources such as solar radiation, wind or water waves. In theory, renewable energy provides an infinite supply of energy.
How does solar energy work?
Solar energy is natural and abundant. The sun is already sending its photons to our planet, burning heat and plant life. Solar panels use only the sun to power the coffee maker.
"All a solar system does is take that energy and convert it," said Asim Hafeez, owner and operator of Empower Energy Solutions, a Connecticut-based solar installer. "Solar panels do not generate energy, they capture the energy that is already affecting our planet."

2018-05-21 121 2 . Solar panels, which are primarily made up of silicon-based photovoltaic cells, absorb some of the energy as most of it is reflected.
3 . The power, in the form of direct current, then passes through an inverter to convert it to alternating current. This is important.
4 . If your house is connected to the electricity grid, the generated energy can be returned to the grid.
5 . Finally, the electrical panel distributes electricity throughout the house, which distributes it to all of your appliances.
Why is renewable energy important?
Coal, natural gas and other fossil fuels are the main causes of climate change, and their supply is limited and will eventually run out. Seeking alternative sources of fuel is in the interest of mankind and it makes sense to use clean unlimited sources available to all.
"As a civilization, our energy consumption has increased," Hafeez said. "If we take energy from a finite source, it's only time to run out. Modern civilization will cease to exist without an infinite source of energy."
Why go to the sun?
Reducing individual energy use may not seem like much, but more people turning to renewable energy sources like solar can make a big difference. But it has other benefits.
"Investing in residential solar is a smart decision for many people who want to reduce their electric bill over time, reduce their carbon footprint and increase the value of their home," said Gilbert Michaud, associate professor at the School of Environmental Conservation. University of California. Loyola University of Chicago. . "Installing solar helps support local jobs for installers and manufacturers."
Here are some pros and cons to consider if you're considering using solar for your home
The advantages are:
- Low Energy Costs: Using the energy from solar panels in your home is much cheaper than getting electricity from the grid. Therefore, installing solar panels will pay off after a few years.
- It's better for the environment: If more people get electricity from renewable sources, it will go a long way in reducing greenhouse gas emissions.
- Solar Power Increases Your Home's Value: According to the United States Department of Energy (PDF), solar panels not only reduce your energy costs, they also increase your home's value.
Cons:
- Solar power has up-front costs: The cost of installing a solar power system can range from $10,000 to $30,000, which is a lot of money, especially in a tough economy.
- Solar might not make sense for your home: If your home doesn't get a lot of sun or your utility doesn't offer net metering, installing solar might not make sense.
- This can require additional work: Before a solar system can be installed, homeowners must remove tree limbs or repair roofs, adding additional costs to an otherwise expensive project.
