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.

The commercialization prospects for fuel cell vehicles depend not only on their performance and cost, but also on how well they can compete with other technology options that address similar market and policy needs. While market forces have not traditionally motivated design change for reasons of environmental performance, customer values and expectations can evolve and such characteristics could grow in importance. However, inherent market conservatism will favor less disruptive ways to address evolving needs, which might be met by improved gasoline and diesel vehicles, including hybrid-electric versions. Yet looking over the long run, particularly the need to substantially reducing greenhouse gas emissions, hydrogen fuel cells may well provide a solution that is superior to other alternatives.

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…)

I just read a very good news via Reuters. And is that the EU has decided to distance themselves from biofuels usage.
As we here at The Green Blog and often Erenovable, biofuels were a good idea that went astray. They are indeed a renewable energy, “but at the expense of what? Of deforestation, increased food prices, and possible food shortages in the future. Not to mention how undeveloped countries such as Brazil and Argentina are ruining their economies and ecologies because of the monopolization of crops for biofuels. (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…)
