Global energy consumption in the last half century has increased very rapidly and is expected to continue to grow over the next 50 years. However, we expect to see significant differences between the last 50 years and the next. The past increase was stimulated by relatively “cheap” fossil fuels and increased rates of industrialization in North America, Europe, and Japan; yet while energy consumption in these countries continues to increase, additional factors are making the picture for the next 50 years more complex. These additional complicating factors include the very rapid increase fuel economy in energy use in China and India (countries representing about a third of the world’s population); the expected depletion of oil resources in the not-too-distant future; and the effect of human activities on global climate change.

One of the most important aerodynamic effects on energy consumption required to keep a body moving through a fluid is the aerodynamic drag force. The drag must be overcome by the thrust of a propulsion mechanism, which in turn is consuming energy. Everything else being equal, the higher the drag, the more energy is consumed. Therefore, for energy efficiency, bodies moving through a fluid should be low drag bodies. To understand how to obtain low drag, we have to first understand the nature of drag, and what really causes it. (more…)

Tanker transportation and oil transport functions as an important link to facilitate the flow of oil and products from their limited sources of origin derived to its destination all over the world. This particular section of ocean shipping industry is the main component of the movement of seaborne cargo. Even though oil is transported through pipelines and tankers and tank wagons, these movements are relatively small and often restricted to national or in a few cases trough the intra-regional trades. The increment in oil demand came not only from the United States & Western Europe, however there is a rapid oil demand recovery in Japan, a country with no domestic oil reserves. (more…)

It is a rare company prospectus that begins with a quotation from Goethe: “Whatever you can do, or dream you can, begin it. Boldness has genius, power, and magic in it.” But Lovins is not a normal entrepreneur, as anyone who has met this eccentric and disheveled but unmistakably visionary thinker knows. The founder of the Rocky Mountain Institute, a leading green think tank based in Old Snowmass, Colorado, thinks the car industry’s incremental approach to cutting emissions and improving fuel efficiency will never amount to much. He wants a complete redesign of the automobile, from the bottom up, and intends to show the big boys how it should be done. (more…)

To that end, the federal government, in late 2008, put in place new incentives – and extended others – designed to create a strong up-tick in sales of unconventional vehicles. As a result, the U.S. Energy Information Administration anticipates that hybrid cars will grow from 2% of new light-duty vehicles sold in 2007 to 38% by 2030. (more…)

Japan has the largest Photovoltaic installed capacity in the world as a result of the sustained investments made by the country through carefully coordinated Photovoltaic R&D and deployment, leading to a ‘‘virtuous cycle’’ among R&D, market growth, and price reduction. By the end of 2000, the total installed capacity in the country was 317 MW, of which on-grid distributed generation accounted for more than 252 MW. In 2000, Japan produced 128 MW of PV cells and 136 MW of modules, both of which were well over half of the global production. (more…)

Not surprisingly, most Energy Research and Development takes place in industrialized countries where both the public and private sectors are involved in the development of energy technologies. Given that most energy technologies are deployed through the marketplace, the predominant focus of Energy Research and Development is within firms. Still, governments have historically played an important role in the Research and Development of new energy technologies through direct financial support (e.g., gas turbines) as well as through policies that promote Energy Research and Development within firms.
