Introduction
In the US, solar energy is one of the most cost-effective ways to generate electricity.

The above chart shows that a solar PV system will save more money than a combined system.
Other methods of generating electricity would cost more than 5 cents per kWh, with large price increases as the years go by.

The above graph shows that wind power is less efficient than other sources of electricity. It also takes place in areas that are far away from where consumers live and use electricity to power their homes and businesses. Solar energy is right around 3 cents per kWh, making it the most efficient form of energy generation in our current society and economy.
Purpose: To show how effective solar energy is when compared with other forms of renewable energy (wind, hydroelectricity, etc.)

Solar energy is clean, renewable, and cost-effective.
Solar energy is a form of renewable energy, and it’s also clean. The sun constantly provides us with heat and light. When solar panels convert sunlight into electricity, they produce no pollution or greenhouse gases like carbon dioxide (CO2).
Solar power has been around for decades—it just wasn’t cost-effective until recently. Once you factor in the cost of installation as well as other factors such as state subsidies and tax breaks, going solar can save you thousands over time compared to using fossil fuels like coal or natural gas.
Solar energy is a form of renewable energy.
The first thing to understand about solar energy is that it’s a form of renewable energy. Renewable resources are those that can be replenished naturally, rather than being mined or burned up in an unsustainable way.
Solar power is one example of a renewable resource; its rays come from the sun and it doesn’t require any additional inputs like coal or oil (which are nonrenewables).
More than half of the world’s electricity comes from renewable sources.
More than half of the world’s electricity comes from renewable sources. That’s because many forms of energy are not destroyed when they’re used, like solar power and wind turbines. Renewable energy is generated from natural resources like sunlight and wind, human activity such as burning coal or oil in power plants, or even nuclear power.
Solar energy costs about twice as much as coal or natural gas.
Solar energy costs about twice as much as coal or natural gas. Solar power is a form of renewable energy and it’s clean, renewable and cost-effective. It’s also free and unlimited!
Less than 3 cents per kilowatt-hour (kWh) is the average cost of electricity from solar power.
Solar power is a renewable source of energy that can be used to generate electricity. The cost of solar power is low, with less than 3 cents per kilowatt-hour (kWh) being the average cost for residential homes in the United States. This means that if you have enough space and sunlight, solar panels will save you money on your monthly bills.
Solar energy also provides clean and reliable power because it doesn’t pollute our air or water like coal-fired plants do; instead they use mirrors or lenses to concentrate sunlight onto photovoltaic cells which produce electrons which are then converted into electricity by inverters inside each panel’s housing unit — no pollution at all!
You can generate solar energy at an average cost of 3 cents per kWh
Solar energy systems are a great way to generate electricity, but you can’t just have one. Even if your area has lots of sunlight, it isn’t enough to power your whole house. You’ll need an efficient solar system that can generate enough energy for all of your needs in the day and night.
The average cost of electricity from solar power is 3 cents per kWh (kilowatt-hour). This means that when you use up all the electricity generated by your solar system during one hour, there will be 3 cents left over after paying for how much power was used in that hour. For example: If you use 100 kW/h in an hour, then there will be about 100 kWh stored in batteries at the end of that hour—but if no more was needed from those batteries during another week’s worth of cloudy days or winter months without sunrises/sunsets (or even just cloudy), then we could say our total costs would only be around $1/day!
Conclusion
How efficient is solar energy?
One of the most common questions we receive is how well solar panels are able to produce energy under various conditions. In this article, I will describe a simple lab experiment that’s easy enough for anyone to perform at home. And if you want to work out even more, here is a link to a complete infographic (a visual representation of data) about the sun’s radiation and how it affects different types of solar panels.
