Renewable Energy Sources in Europe: Geothermal, Wind Energy, Biomass

In Europe, modern renewable energy sources technologies were explored thoroughly for the first time after the oil embargo/ price crisis of 1973. Notably, market introduction of renewable energy technology started in about 1985, but the renewable energy sources industry has become vital only during the past decade. Accordingly, relevant statistical renewable energy sources data have been systematically compiled only over the past decade, although reliable and consistent statistical renewable energy sources data, collected since 1989, exist for all 15 countries of the European Union and for Western Europe (defined here as the EU-15 plus Switzerland, Norway, and Iceland).

Renewable Energy Technologies in Europe

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…)

Economics Value of Energy

We have seen that energy is basic for life and activities in nature and society. Energy is a measure of value in physical terms. However, the more complex a system or a process becomes, the less can be said by physics. Even the term ‘‘complexity’’ is problematic. There are several definitions of complexity as a quantitative concept in information theory. (more…)

Choosing Alternative Energy Investment – Funds and Stocks Market

With popularity of clean energy, the reduction of carbon and the movement toward earth friendliness, it seems that investment in alternative energy fund would be virtually no risk. But like any new industry, there is no guarantee that all sectors of the market will be successful. Since the technology bubble, which began in the early and mid 90s the market for alternative energy will soon separate winners from losers. If you are lucky or wise enough to choose an achiever, you soon will be getting great gain in your investment. On the other hand, losses are for those who have taken up the approximation that was not well received by the substantial market. (more…)

Theoretical Issues in Energy Taxation

The primary purpose of all forms of taxation, whether on energy or on non-energy items, is to raise money for the government to finance its expenditures. Taxes finance the majority of government expenditure (the rest being financed by borrowing, which will have to be repaid from future taxation) so that the general level of taxation is determined by the requirements for government spending. However, the same total revenue can be raised by many different combinations of taxes, so that the tax rates on individual items and groups of items can be adjusted to reflect other criteria.

The issues of hydrogen storage run through the hydrogen production, hydrogen transport, supply and demand for end use of hydrogen as an energy sources. (more…)

Virgin Biomass as Source of Renewable Energy

virgin biomass renewable energy
The most widespread and practical process for capture solar radiation as organic fuels is the growth of virgin biomass. Extremely large quantities of carbon are fixed each year in the form of terrestrial and aquatic biomass. (more…)

Environment, Economy, Energy, and Sustainable Development

environment energy sustainable development
The convention aims not only at stabilizing CO2 emissions in developed countries but also at ultimately reducing man-made CO2 emissions globally so as to stabilize the global climate. Environmental degradation cannot be singled out as an independent matter among various global issues. (more…)

The hydrogen can come from various sources including fossil fuels, wind, solar, biomass, nuclear, solar thermo-chemical reactions, and solar photolysis. (more…)

The Importance of Solar Energy and Home Ventilation

home solar energy
Our homes collect large amounts of solar energy, our homes when built are often placed on our sections to get the best solar energy from the sun, even years ago before we thought of using solar energy to heat or dry out your home the builders did this. We have known for years that the sun can be used to make our home feel warmer and better to live in. In fact in winter we look to find the warmest part of the home to sit to study or watch TV. If your home was placed well on your section this room is likely to be your lounge or conservatory. What about your bedrooms or study how do they get warmth and fresh air? (more…)
