Quick Facts About Renewable Energy and Smart Grid

There are signs that renewable energy is being harnessed throughout Ohio, whether it is large areas of wind turbines or solar panels, including some on rooftops. Renewable energy is energy created by sources that either don’t run out or are easily replenished, like the sun or wind. Consumers should understand these two renewable energy sources and what “smart grid” means.

Solar Power

Solar power is a renewable energy source using the sun to generate electricity. Solar panels collect the sun’s energy to convert it into electricity. The more sunlight that hits a solar panel, the more electricity it produces.

In Ohio

Ohio could have a bright future for solar power since it averages over 170 sunny days per year. In 2026, Ohio had an installed solar capacity of 7 gigawatts (GW)—enough to power almost 862,582 homes.

Benefits and concerns 

Solar power is a clean and renewable energy source. It allows for energy production at home which can lower electricity bills. Solar power can also help to reduce dependence on imported and domestic fossil fuels. Some issues remain, such as how to dispose of worn-out panels.

Residential systems

A residential solar power system can be expensive. On average a typical installed a13.42 kilowatt (kW) solar panel system can cost about $37,700, according to EnergySage. As demand increases, and financial incentives continue, solar power may be a realistic investment for many Ohioans, depending on how much sun the panels can get.

Be cautious of solar power companies selling overpriced or inferior products. It is recommended that consumers considering home solar do careful research and get competing bids. Contact several installers and always check with the utility before purchasing. Don’t rush into a decision because of high-pressure sales tactics. Understand the contract and ask questions. Know if it is a purchase or a lease, and what happens if panels need repair or don’t perform as promised.

Wind Power

Wind power uses turbines to capture the wind’s energy and converts it into electricity. Turbine blades spin when the wind blows and the blades turn a generator that produces electricity.

In Ohio

As of June 2026, there are 22 utility-scale wind farms in Ohio, according to Cleanview’s project tracker. According to the U.S. Energy Information Administration, Ohio had 1,100 megawatts of installed wind generating capacity in mid-2025. Another 437 megawatts  is scheduled to come online by the end of 2026.

Benefits and concerns 

Wind power provides electricity without burning fuel to pollute the air. According to the American Clean Power Association, wind turbines in the United States are already reducing carbon emissions by over 100 million tons per year. Wind power critics say that turbines are an eye-sore, produce noise and may disrupt wildlife even though other electricity generation sources have similar negative impacts. Continuing research may help reduce these concerns.

Wind and Solar Power’s Future

Most of the wind turbines in use today are on land. However, more offshore wind sites are being built. The first offshore wind farm was built off the coast of Rhode Island in 2016. Wind turbines may be coming to Lake Erie in the not-too-distant future. The U.S. Department of Energy’s Wind Vision Study indicates that wind energy could provide 35 percent of the nation’s electricity by 2050.

Improved energy storage technology can help wind and sun’s ability to meet energy needs, even at night and on windless or cloudy days.

Renewable Energy Choice

Ohio consumers have the option to choose who provides their electricity. Some marketers and governmental aggregators may offer green energy options. Always compare prices when considering these offers. Consumers should avoid “greenwashing,” which is a deceptive marketing tactic that could under-deliver green energy and over-charge them.

Smart Grid

The smart grid is a modern electrical network that uses digital technology to improve efficiency and reliability. It has the potential to reduce power outages, improve energy efficiency, and integrate renewable energy sources.

The smart grid uses sensors and communication technology to monitor the flow of electricity in the grid. This information can be used to optimize operations and prevent problems. Smart meters are installed in homes and businesses as part of the smart grid.

Unfortunately, as of now Ohio utilities can use the smart grid to charge consumers more and to make it easier to disconnect service while consumers are not seeing all the smart grid benefits.

Consumers not wanting a smart meter can usually opt out for a fee and get a meter without the smart-meter communication systems. Check with your utility for details.
