Will Solar Panels Generate Enough Energy To Sustain The World

Keep in mind that the amount of power your solar system can produce depends on how much sunlight your roof receives and your location.

Will solar panels generate enough energy to sustain the world.

Not only can you easily generate enough energy to cover all of your energy needs but solar panels are now cheaper and more efficient than ever. Solar is driven by rapid expansion particularly in developing countries as it is gradually gaining stance as the most desirable option for securing power. Now if we cover an area of the earth 335 kilometers by 335 kilometers with solar panels even with moderate efficiencies achievable easily today it will provide more than 17 4 tw power. At 2 8 acres per gwh then about 11 200 000 acres of land would give us what we need to produce the 4 000 000 gwh of solar power.

It is technically possible to achieve almost 100 renewable energy sources within the next four decades concludes the world wildlife federation s wwf 2011 energy report which sees wind solar biomass and hydropower as the future major players. Solar would have to produce about 4 million gwh of electricity annually to provide enough energy to power the entire usa. There s 1 8 billion acres of land in the usa so about 0 6 of our land is all it would take. A 10kw solar system which consists of 40 panels can produce an average of 14 000 kwh per year.

A single solar farm large but contained to a single u s. Return to how do solar panels work. You will need a roof space of about 680 sq ft for a 10kw system. This is about the size of spain although as the author notes the sahara desert alone is 18 times the required size so lack of available land shouldn t be a problem.

Currently solar photovoltaic technology makes up 55 percent of all renewable power capacity and it will continue to boom according to a 2018 reporton the state of renewable energy. Another report suggests that we d need to cover 191 817 square miles of surface with solar pv panels to produce enough power to support the world.
