Since the availability of different RES is dependent on the region, it is necessary to find the most effective combination (mix) of the various forms of RES to obtain maximum output. In the end, it makes no sense to use one single RES – especially when thinking of the enormous possibilities available in the various fields of renewable energy sources. Unless fossil energy sources and other traditional energy sources, like nuclear energy, renewable energy sources are inexhaustible.
Eventually, fossil energy sources and other traditional forms of energy sources have become a major factor in the political, social and economic life of states. Depending on the level of industrial development the securing of energy sources has become one of the most important goals of these particular states.
The origins of fossil energy sources lie in the early stages of evolution. Then, Plants, like those today, bound carbon dioxide (CO2) by means of photosynthesis and produced oxygen as a by-product. This process was essential within the evolutionary process in order to bind the, for human beings and other aerobic organisms, toxic gas of CO2 and to provide those aerobic organisms with an oxygen atmosphere. Chemical processes, under pressure, transformed these plants, after they died, over an extended period into the commonly known fossil fuels – coal, oil and natural gas. By burning these fossil fuels the reverse reaction of this CO2 binding process of plants of million years ago takes place. The CO2 gets released again and the human beings essential oxygen gets used up. The consequences are known – global warming, greenhouse effect etc. This is only one problem related to the burning of fossil fuels.
Since fossil fuels are only limited in their amount, the dependency on fossil fuels will become a risk. The availability of fossil fuels is different within the categories of coal, oil and natural gas. Even the numbers when those sources run out exist in a huge amount. For the different sources the following average numbers are available.
The first fossil fuel that will run out is the most valuable in terms of the need in industrialized countries – oil. With an increasing demand of oil the optimistic expectations when this source of energy will run out is 35 years. Although, there are optimistic views that oil deposits will be discovered in the future and those that are hard to reach today will be exploited, it is fundamentally the case that the major oil deposits have been discovered and are already being exploited. It is also the case that even if those new or hard to reach deposits should be exploited, the costs in general, dangers and risks for the environment (remote areas like the Amazon rainforest and oil fields in Alaska) will be impossible to calculate.
The next fossil source that will run out is natural gas. This source, with an increasing demand, will possibly run out in the year 2040. Since, companies involved in the energy sector are currently running a big campaign to promote
The events during the oil crises with the immense increase of national debt in the case of developing countries should have taught us a lesson. When not learning from this lesson, events like the oil crises will be bring even more suffering. Especially when thinking of the fight for resources in the near future. By becoming independent from traditional energy forms events like the oil crises have no possibilities to concern states, which are energetically independent. With correct implementation of renewable energy sources and their technologies new forms of colonialisation by the West will have no opportunity to grow.
The security political aspect of RES becomes evident when looking at its decentralized nature. Due to the fact of new ways of threats to the sovereignty of a state new ways of defending have to be found. One vulnerable aspect within a state system is its energy production. Energy production that is decentralized becomes less vulnerable to outside attacks than a centralized energy production. Not only is the result of an attack on a centralized energy system a break down of energy supply but other disastrous factors have to be taken into account as well. When thinking of a hydropower plant the destruction of areas below the dam becomes enormous. With nuclear power plant the destruction is not only limited to a certain period of time but the consequences will be evident for years and even decades and centuries due to nuclear radiation.
When looking at the economic advantage of RES it is apparent that they can serve as a new root for economic growth. Since each region or state will use a different mix of renewable energy sources, each region or state will want to have the opportunity to produce this energy mix by itself. The advantages should be clear. The revitalization, development and extension of local industry in various sectors - agricultural sector, metal industry, research etc.
In fact, there are concrete numbers to what extent different RE sources bring economic growth. With the implementation of new laws in Germany regarding RES a boom for PV and solar collectors has been initiated. The result was an increase of investment in research on the one hand and the establishment of new local industry for the production of PV panels and solar collectors. The new laws in Germany have created 70000 new jobs.

The problem is implementation Antony Felix O. O. Simbowo | May 7th, 2005
Its sad that places like Sub Saharan Africa with plenty of sun and wind are still wallowing in energy deficits...
Pundits like you should help people like us in the developed world to lobby our governments to form tangible frameworks on the wholescale adoption of renewable energy sources. The winning of the Nobel Prize by Prof. Maathai adds a voice but still seems inadequate...Its here that we need vocal back up...For how long are we going to depend on hydro electricity with the perilous global warming catching up on us?
