Description:
The majority of energy is currently produced by the use of fossil fuels (oil and gas). At this moment the European Union region does not have any major deposit of these types of resources, being almost completely dependent of external suppliers (Russia and Middle Eastern contries).
Renewable sources of energy are an alternative because they can be easily replenished and generated using available resources like waste, Sun and wind. If the researches that are being at this moment, the European Union can become more independent of external fluctuations of prices and supplies of those fossil fuels.
Enablers:
They will last forever as they use energy generated by the sun or wind.
Wind power mitigates the emission of greenhouse gases and therefore reduces global warming
Increasing awareness of the need for the conservation of fossil fuels
Increasing cost of traditional sources of energy i.e fossil fuels
Dangers of alternatives including nuclear energy
Inhibitors:
Not aesthetically pleasing e.g wind turbines
Hazardous to ecosystems e.g. dams create barriers for migrating fish,
Extensive land use is required which could otherwise be farmed
Availability not consistent
Paradigms:
For 30 years, governments and international institutions have been aware of the limits of conventional energy and its broad damaging consequences. However implementation of renewable sources of energy have not progressed as fast as fossil fuel energy consumption has increased. Governments have tried to reach a global consensus for action which instead leads to paralysis. As a result, world civilizations are still dependent on fossil fuels. Less than 20 billion dollars of the tax payers’ money was spent in the last 30 years to promote renewable energy as opposed to 1 trillion spent on atomic energy research.
Experts:
Petroleum geologists
