Welcome to the Energy Blog

  • The Energy Blog is where all topics relating to The Energy Revolution are presented. Increasingly, expensive oil, coal and global warming are causing an energy revolution by requiring fossil fuels to be supplemented by alternative energy sources and by requiring changes in lifestyle. Please contact me with your comments and questions. Further Information about me can be found HERE.

While it may help for a while, please remember that GT energy is not renewable, at least on human timescales. It amounts to heat mining the earth's crust.

Back in the seventies and eighties the Oil companies knew there would be interest in this area of energy. So the Oil Companies purchased all the rights to the existing known geothermal sites. If you are interested in details there was a write up a few months ago stating the same content I am providing as to whom owned the rights to each geothermal port and the land around each port. Smart investing on the Oil Companies, bad news for the global environment.


Unless the water is recycled by condensation of the steam, geothermal is too expensdive in terms of water use. aquifer depletion, and pollution.

Water recycling would most likely make this source too expensive, just as actual sequestration of cO2 by pumping it underground would make clean coal too expensive.

And the total 10% of present generating capacity doesn't even make this worth the effort. It's another boondoggle like fuel farming. An excuse to divert resources that would otherwise go to replace the ICE and oil consumption.

On the other hand, geothermal for heating/cooling could save around half of our present generating capacity. That's the right way to use geothermal. But for the most part government and indiustry are not interested.

It's a technology with no big lobbying behind it. Instead funds and attention are diverted away from it by industries that make more money as energy demand rises.

Wind power can provide the other half of needed generating capacity with biogas from waste used in fuel cells for backup. MIT has been consistently less than helpful in most of its recent energy/climate change efforts, with the exception of the A123 battery.

This is dissappointing considering MIT's key role during WW2. Why not join the fight MIT? Break free of your corporate overlords.


If you have looked into solar energy as a method for heating your home, panels are usually the first things that come up.

There are, however, other unique methods.

The Solar Heating Aspect You Have Never Heard of Before

The power of the sun is immense. The energy in one day of sunlight is more than the world needs. The problem, of course,

is how does one harness this power. Solar panels represent the obvious solution, but they have their downside. First,

they can be expensive depending upon your energy needs. Second, they do not exactly blend in with the rest of your home.

Passive solar heating represents a panel free method of harnessing the inherent energy found in the sun for heating

purposes. If you come out from a store and open the door of your car in the summer, you understand the concept of passive

solar heating. A wide variety of material absorbs sunlight and radiates the energy back into the air in the form of heat.

Passive solar heating for a home works the same way as the process which overheats your car in the parking lot.
