Vulcan Power Company – Thermal Energy Isn't Just Hot Air

Everyone has heard of solar and wind technology by now. But it does not ordinarily occur to people that they are standing on top of an immense core full of another form of power. It is a privilege to see hot lava slowly oozing its way to the ocean in areas where one can do so safely – such as in Hawaii. Steam rises from the hot crust and the red glow of the molten rock reminds onlookers what may be rolling around only a few meters underneath the cooled crust they are standing on. Lava is the molten rock that has made its way through a weaker area of the earth’s crust, but just 7 miles under our feet – no matter where you are – is where the outer mantle of the earth begins and where temperatures rise to 2500 degrees Fahrenheit. Geothermal technologies use heat found in some shallower areas where the temperature is much lower and safer to work with – ranging between 100-300 degrees Fahrenheit.

Vulcan Power Company (“Vulcan”) is focused on developing geothermal power plants. According to their website, it is estimated that Vulcan properties will supply sufficient electricity for up to 2 million Americans. Thinking at a larger scale; Geothermal power can provide electricity for 15% of the world’s population!


Geothermal energy comes primarily in the form of heat or steam and is mostly available in the Western part of the U.S, Alaska and Hawaii. There are many benefits to using geothermal power. Vulcan explains this in their website: “When properly developed and monitored, geothermal steam resources are renewable. Cooler fluids exiting power plants are reinjected and reheated in subsurface reservoirs on a sustainable basis. Modern geothermal power projects have minimal impacts on air, land and water ecosystems. Some consider geothermal to be the lowest impact power source. It has much lower environmental impacts than hydro, nuclear, coal, oil or gas fired or windpower plants. Geothermal plants are relatively small in size and have been permitted in national forests and fragile high desert valley environments where other power plants are not allowed.”

The main benefit is that thermal power is clean; No fossil fuels are burned and the carbon dioxide emissions are 1/6th of the cleanest alternative power-plant. Secondly, this resource will not be running out any time soon and is renewable. Finally, it is a local resource and dependence on foreign oil – which also goes hand in hand with frustrating energy price fluctuations – will be a thing of the past.

The next step would be to figure out how to take advantage of the immense heat emitted directly from the lava. As for right now, we are literally walking on top of an endless amount of “fuel.” The potential for geothermal technology is immense and as stated by Vulcan “Full Steam Ahead!”

    There is increasing concern that governments are allowing companies to reduce the price paid to producers of exported renewable energy. Large banks and organizations dominate the large scale markets of renewable energy generation that have up till now made significant profits in the current climate.

    The price of energy doesn´t seem to get cheaper – clearly the changes must be made within each of us and adopt our own renewable energy generating capabilities and reduce our demand on expensive, fluctuating imported energy.

    Verdegía in Spain have a solution, Solar Engine Systems that generate plenty of green energy. If we ourselves, government and councils adopted this type of new technology then we could all very quickly change the effects of our demand on fossil fuels. – The Solar Engine Systems supplied from Verdegía boast 39kW/h and operate 24/7. That´s enough energy for 12 or more homes! And, they only take up the space of a single 200W PV panel.

    A major cost in renewable energy farms is the infrastructure, land and high capital investment, producing electricity locally within a distributed network is the most cost effective. It’s time to move away from large expensive solar farms and into the next generation of high performance renewable energy generators that effectively create a solar farm within one panel and at a 100th of the cost. This technology will allow us to turn vacant city rooftops into a hive of renewable generators that will not only feed our cities but will provide energy independence.

    Imagine a future where electricity was FREE and in public places you could just plug in and know that the energy being consumed has come from 100% renewable sources.
