solar power the way of the future...

efficiency

solar power only has about a 22% efficiency rate.

solar is not practical in most places except for in the tropics or in deserts. These are the best places to use solar power. But there is usually natural dangers like dust storms and tropical flooding.

space

• would have to cut down rain forests to fit the space requirement.
• would have to put it in remote areas where the building of infistucture would be needed.
• to produce 1 Gw of power you'd need about 14sq miles of land.

expenses

where there is a high solar radiance there tends to be less people and poverty.

as you can see the relationship between the two maps.
