Yes, there are those who still curiously regard fossil fuels as the only realistic energy sources for our world. It is a dead-end if there ever was one; an idea largely propagated by the fossil fuel biz and their political front men and women. Thankfully, for those who understand the inescapable necessity of renewable clean energy, the options just keep growing.

Meet the solar tower, a solar-based energy source that is an intriguing mix of solar and wind energy. A company named “Enviromission” has its sights on Arizona to build this massive tower. It’s essentially an enormous greenhouse that traps air heated by the sun’s rays. Hot air naturally rises, and as the air does so it is funneled through a central point (the tower), the base of which sports an array of fans that are turned by the current just like a windmill.

A detailed description of the tower can be found here including its numerous advantages. For starters, it is low maintenance, continues to work at night, has zero GHG emissions, makes use of essentially useless desert, and the list still goes on. This earlier, smaller version in Spain recently achieved the huge milestone of generating twenty-four hours of uninterrupted supply, proving solar energy can provide power well into the night!

This is just one of many options that are currently available and make the reality of renewable energy all the more imminent. Add some wind energy, solar thermal and solar PV, some geothermal for good measure, and we’re well on our way to a cleaner, sustainable future.
