(January 2009) Schematic of the current sources of energy Energy development is the effort to provide sufficient primary energy sources and secondary energy forms to fulfill civilization's needs. It involves both installation of established technologies and research and development to create new energy-related technologies. Major considerations in energy planning include resource depletion, supply production peaks, security of supply, cost, impact on air pollution and water pollution, and whether or not the source is renewable. Technologically advanced societies have become increasingly dependent on external energy sources. Research, development and practice of energy efficiency and conservation by the populace allows a degree of mitigation of this dependence. Wise energy use embodies the idea of balancing levels of human comfort and energy consumption by researching and implementing effective and sustainable energy harvesting and utilization measures.

Alternative Energy? (Answers: 13) (Comments: 0)

I've read reports that by 2030, 115 million barrels of oil need to be produced to the meet the increase needs of China and India. This particular author advocated highly for alternative energies. However, I read another source, where the argument was that alternative energies were just as harmful to the environment. It is clear that the stifling need of fuels from over-populated India and China pose a large challenge, but is alternative energy the answer? Is there really enough oil to last us at least a century as some sources suggest? It's difficult to get the truth from so many differing biases on our economy and fuel-usage.

Alternative energy? (Answers: 3) (Comments: 0)

What do you think will happen once oil and natural gas start becoming really scarce? I read somewhere that the world could survive with 20/30% less energy because so much is wasted but then what? What if the supply decreases by 75%? Judging by prices alone i would say that current supply is at best "tight" and will slowly decrease worldwide in the years to come. Will alternative energies, even the ones that supposedly work (and they might not), be at least available when needed?

When are alternative energy stocks going to rise? (Answers: 5) (Comments: 0)

Obama seems to be the ultimate alternative energy supporter, so I suppose that alternative energy stocks will rise under his presidency. The oil price is down a lot right now, and that doesn't support investments in alternative energy; I also heard that oil companies will fight to death to stop alternative energy companies from taking off. When is going to be the best time to invest in solar, wind and hydrogen?
