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…)

Although the automotive industry is a vigorous sponsor of research and development in vehicle efficiency technology—worldwide, nearly $20 billion U.S. worth in 1997—governments throughout the world sponsor additional automotive R&D, both separately from and in partnership with the industry. This work focuses primarily on four areas: emissions reduction, safety, fuels, and fuel economy. Within the past few years, government sponsorship of automotive R&D has moved sharply in the direction of attempting to advance the performance and cost-effectiveness of automotive fuel cells vehicles, which address three of the four areas: emissions, fuels, and fuel economy.

The most commonly researched and most developed application of using hydrogen as a fuel source is in conjunction with a hydrogen fuel cell. Fuel cells operate by mixing hydrogen and oxygen to produce water and electricity. The electricity can then be used to provide power to homes, schools, and even businesses or to power cars and other vehicles. Some experts believe that internal combustion engines (ICEs) that are fueled by hydrogen are just as important. Hydrogen could be used as fuel for transportation by creating internal combustion engines for vehicles that run on hydrogen or hydrogen fuel mixtures. (more…)
