How Much Of The World Uses Solare Panels

As of the beginning of 2016 the total world pv capacity was 303 gwh or about 1 8.

How much of the world uses solare panels. To power 4 6 million homes reducing harmful carbon emissions by more than 25 million metric tons a. The exact number changes depending on the specifications of the chosen panel model as well as the sunshine available at the project site. Before purchasing a solar energy system for your home an important step is finding out how many solar panels you need. Here is a table with the top 10 counties listed.

At over 20 gigawatts of installed solar electric capacity we now have enough solar in the u s. The previous section looked at the energy output from solar across the world. The more meaningful number is what percentage of the electricity produce comes from solar energy. Italy uses 16 361 mw china uses 8 300 mw usa 7 777 mw japan 6 914 mw spain 5 166 mw france 4 003 mw belgium and australia uses 2 650 mw each czech republic uses 2 072 mw.

While more capacity was installed in 2017 the global growth rate slowed last year down from 49 percent in 2016 according to energy news site cleantechnica. The global solar market grew 29 3 percent last year with nations installing 98 9 gigawatts of new capacity according to data from the industry group solarpower europe. The top installers of 2016 through 2019 were china the united states and india. World wide the number is still pretty low.

A home that consumes 1 000 kwh per month will normally need between 20 and 30 solar panels. Most of the other 82 was used for heat and transportation. Energy generation is therefore a function of how much solar capacity is installed. In 2016 the total world energy came from 80 fossil fuels 10 biofuels 5 nuclear and 5 renewable hydro wind solar geothermal.

Energy output is a function of power installed capacity multiplied by the time of generation. The use of solar panels to obtain electricity and heat is growing but it is still extremely small when compared to other types of energy. How much solar energy is used in the world. This interactive chart shows installed solar capacity across the world.

The new capacity brings the total operating solar power in the world to 405 gw 89 percent of which was installed in the last seven years according to iflscience. By the end of 2016 cumulative photovoltaic capacity increased by more than 75 gigawatt gw and reached at least 303 gw sufficient to supply approximately 1 8 percent of the world s total electricity consumption. It is estimated that only 1 percent of the united states electricity and power come from solar panels and solar energy which is hardly enough to make a difference in the amount of fossil fuels used.
