Key takeaways –
China uses the most solar power globally, generating over 224 GWh of electricity using just solar, with a projected 370 kWh of installed solar by 2024. Government incentives are the largest driver of solar power and many countries are embracing a renewable energy transition to enhance their economies for a post-COVID world. Solar installations are becoming cheaper and are expected to increase in both residential and commercial U.S. markets – with the potential of 1 solar installation per minute in the US by 2024.

What is solar energy most commonly used for?
Solar energy is a powerful source of energy that can be used to heat, cool, and light homes and businesses. Text version More energy from the sun falls on the earth in one hour than is used by everyone in the world in one year. A variety of technologies convert sunlight to usable energy for buildings.
The most commonly used solar technologies for homes and businesses are solar photovoltaics for electricity, passive solar design for space heating and cooling, and solar water heating. Businesses and industry use solar technologies to diversify their energy sources, improve efficiency, and save money.
Energy developers and utilities use solar photovoltaic and concentrating solar power technologies to produce electricity on a massive scale to power cities and small towns. Learn more about the following solar technologies:
Which country has the most solar?
Key Takeaways –
China leads the world as the top producer of solar energy, installing more than 48 GW of photovoltaic (PV) capacity in 2020.The EU, the United States, Vietnam, and Japan are ranked as top solar producers.A gigawatt (GW) is a unit of measurement of electrical power.Photovoltaic (PV) technology converts sunlight into electrical energy.
How common is solar energy?
Solar power is more affordable, accessible, and prevalent in the United States than ever before. From just 0.34 GW in 2008, U.S. solar power capacity has grown to an estimated 97.2 gigawatts (GW) today. This is enough to power the equivalent of 18 million average American homes.
- Today, over 3% of U.S.
- Electricity comes from solar energy in the form of solar photovoltaics (PV) and concentrating solar-thermal power (CSP),
- Since 2014, the average cost of solar PV panels has dropped nearly 70%,
- Markets for solar energy are maturing rapidly around the country since solar electricity is now economically competitive with conventional energy sources in most states.
Solar’s abundance and potential throughout the United States is staggering: PV panels on just 22,000 square miles of the nation’s total land area – about the size of Lake Michigan – could supply enough electricity to power the entire United States, Solar panels can also be installed on rooftops with essentially no land use impacts, and it is projected that more than one in seven U.S.
- Homes will have a rooftop solar PV system by 2030.
- CSP is another method for capturing energy from the sun, with about 1.8 GW of capacity in the United States.
- The cost of electricity from CSP plants fell more than 50% from 2010 to 2020.
- If CSP cost reduction targets are met, studies show it could provide up to 158 GW of power to the U.S.
by 2050. Moreover, the solar industry is a proven incubator for job growth throughout the nation. American solar jobs have increased 167% over the past decade, which is five times faster than the overall job growth rate in the U.S. economy. There are more than 250,000 solar workers in the United States in fields spanning manufacturing, installation, project development, trade, distribution, and more.
Solar energy hasn’t reached its full potential as a clean energy source for the United States, and significant work remains to be done to drive deployment of solar technologies. Solar hardware costs have fallen dramatically, but market barriers and grid integration challenges continue to hinder greater deployment.
Non-hardware solar ” soft costs “—such as permitting, financing, and customer acquisition—are becoming an increasingly larger fraction of the total cost of solar and now constitute up to 65% of the cost of a residential PV system, Technological advances and innovative market solutions are still needed to increase efficiency, drive down costs, and enable utilities to rely on solar for baseload power.
Can solar energy be used in transportation?
Some car manufacturers are already using solar panels to aid electric batteries. The Toyota Prius plug-in, for example, has a solar panel on the roof that charges while the vehicle is parked. Solar energy is then used to power the sat-nav and air conditioning.
