The development of the ‘‘new’’ wind and solar technologies is of great importance for the future contribution of RESs to energy supply. Although the present wind and solar technology contribution of 0.4% to total primary energy consumption per capita is still very small, the growth of these industries has been considerable in the past 6 to 8 years. Today they provide 10 times the energy of 10 years ago. Wind energy shows the most remarkable growth dynamics; its contribution is now reaching energetically relevant dimensions. (more…)

Nuclear energy has some distinct advantages in strengthening the external dimension of energy supply security. These include:
• Nuclear power plants produce electricity domestically. Their capital and labor inputs are also provided domestically. With more than 90% of its inputs in terms of value sourced domestically, it can be considered a largely domestic source of energy and electricity.
• Of course, a majority of OECD countries import part or all of their requirements of uranium plutonium. (more…)

Agricultural and forestry residues provide the largest proportion of biomass used for the production of biomas bioenergy. Some estimates suggest that globally available biomass role in the form of recoverable residues represents about 40 Ejyr -1, enough to meet 10% of the total present energy use of 406 Ejyr -1 . However, realizing this potential is limited by factors such as ease and cost of recovery and environmental concerns relating to sustainable land use practices. (more…)

The accumulation of carbon within a forest growth cycle can be considered in four stages. The initial establishment stage involves low global carbon cycle accumulation and may even experience net carbon loss (particularly from soil) as a result of site preparation and low biomass and bioenergy inputs. A rapid uptake of carbon is then experienced during the second phase, known as the full vigor stage, which subsequently levels off as the stand reaches the mature stage. Finally, the forest reaches old growth and the carbon is in steady state with accumulation associated with new growth balanced by mortality and disturbances. (more…)

Geothermal energy is energy created by the heat of the Earth. Under the Earth’s crust lies a layer of thick, hot rock with occasional pockets of water. This water sometimes seeps up to the surface in the form of hot springs. Even where the water does not travel naturally to the Earth’s surface, it is sometimes possible to reach it by drilling. This hot water can be used as a virtually free source of renewable energy, either directly as hot water, steam, or heat or as a means of generating power. Geothermal energy as renewable energy is nonpolluting, inexpensive, and in most cases the sources is renewable. (more…)

Renewable energy sources cannot run out and causes so little damage to the environment that its use does not need to be restricted. No energy system based on mineral resources is renewable because, one day, the mineral deposits will be used up. This is true for fossil fuels and uranium. The debate about when a particular mineral resource will run out is irrelevant in this context. Renewable energy sources are replenished continuously.
Renewable energy sources—solar, wind, biomass (under specific conditions), and tides—are based directly or indirectly on solar energy. Hydroelectric power is not necessarily a renewable energy source because large-scale projects can cause ecological damage and irreversible consequences. Geothermal energy heat is renewable but must be used cautiously to guard against irreversible ecological effects. (more…)
