1.3.2 Renewable Energy

What is it?

Any source of energy that can be replenished faster or as fast as it is being used is per definition a renewable energy source. The burning of fossil fuels & thermo nuclear energy is not regarded as renewable energy forms.

Where is it?

To have renewable energy you needs to capture it from a natural source that contain energy. Wind, Light and Flowing Water are the most common energy sources. As flowing water has a much higher density than wind, it is much more efficient as an energy source. A large wind turbine is required to capture the wind, but a small water turbine might capture the same amount in water. Solar Panels can convert up to 40% of the light that hits them in the best case scenario, but due to their small format and long life cycle they are ideal for powering remote equipment of different types.


Renewable Energy is a commonly referred to by many in the public discourse, and it seems to have become more so in the current strained financial times[1]. As one can see from the google trends graph below, the interest and media coverage is high and rising:

The ongoing climate debate does also push for action and the decision makers are moved towards this field as government funds globally feels more just if spent on this cause rather the banks and financial systems. Change is needed and it should and will come from this field, but tradition, cost, legislation and expensive infrastructure are dampers on development.

President Obama is trying to start a shift towards an industry that will produce renewable energy technology and equipment and is using government funds through the American Recovery and Reinvestment Act to stimulate this development. This stimulus is part of the plan to get back up again after the crisis that has hit American finance and automotive industries quite hard[2].
