Alternative energy is attractive options
The traditional form of energy worldwide refers to fossil fuels. This term includes motley of crude oil, petroleum products, coal and the like. Fossil fuels are carbon-derived substances that have formed from the remains of dead organic matter in a time period spanning millions of years. As an energy source, their supplies are limited and can not recover. Moreover, the irresponsible consumption of coal and oil in the world, of course, has drawn attention to the environmental hazards of this type energy. Global warming, the rising incidence of asthma and several other diseases can be attributed to increased burning of fossil fuels. As a result, the need the adoption of alternative modes of energy has been felt sharply in recent times. Various types of alternative energy sources have been developed to varying degrees. In the following sections, we briefly discuss four major forms of alternative energy.
Hydropower: Antigua and developed so
The energy from the water known as hydropower. This essentially uses the force of falling water, as seen in a natural waterfall, turn turbines to generate mechanical or electrical energy. Hydropower is one of the oldest and most widely used of alternative forms of energy. The regions that have a number of rivers and streams make fertile ground for the construction of dams to store water in large quantities. Hydroelectric dams can provide power to an entire city at cheap rate. However, the construction and operation of hydroelectric dams involving finance and considerable experience, respectively. An index of the popularity and success of this mode can be gauged by the fact that currently, nearly 20 percent of power the needs of mankind throughout the world are being met by hydropower. In addition, hydropower accounts for nearly 90 percent of all the power generated worldwide by the combination of various alternative forms of energy.
Wind Energy: feasible but unreliable
Using wind power to generate electricity recommends itself as a form of alternative energy in his being inexpensive, easy to operate and environmentally friendly. The areas that are home to strong winds which are ideal places for the installation of windmills. These regions can happily use their strength to turn windmills that can be used to generate lots of electricity. Windmills are easy to build and strength of the winds makes it move, and eventually generate electricity. However, on the other side, the winds have no reason to be on time, so to speak, and thus make for an option reliable. The associated technology is being used successfully in various parts of the world. The Netherlands has become an excellent example of effective use of this type of alternative energy.
Nuclear energy: a controversial option
Nuclear power has the potential to generate large amounts of electricity. However, this mode has certain risk factors inherent and can not be ignored. In fact, nuclear technology remains the subject exclusive of an elite group of some of the nations. The fear of misuse of technology and related materials are very real in today's terror-shaken world to be ignored by complete. More than 14 percent of global electricity in 2007 came from nuclear power plants.
Tidal power for the coast areas
The tides that occur naturally in coastal areas are a clean, renewable and alternative energy economically. This mode uses the place and reflow tides that occur due to interaction between the gravitational forces of the Sun, Earth and Moon. Since tides are not weather dependent, their movements are predictable with a reasonable degree of accuracy. The movement of tidal waves in the first place, is used to fill the water reservoirs. The water is then released through turbines that generate electricity.

best solar backpack charger?
Backpack Solar Chargers vary in price dramatically. I've seen $ 200 backpacks and $ 99. quality (all are low China) sometimes the lights go out in my area all day. So I want a reliable. Until now I have a face solar USB charger, which does not have anywhere near the load. The experts say: "I need more intense light, it is winter, blah, blah, blah" I'd love to hear your opinion. Thanks
You may have to change a bit, but I use my VW solar panel for almost everything. http://shop.ebay.com/?_from=R40&_trksid=m38.l1313&_nkw=VW+solar&_sacat=See-All-Categories

A google search of …
A google search of “elevator return energy”, found that modern elevator systems in tall buildings do have special drive mechanisms that generates return energy when the elevator is going down. Thus, the complete needed technology for storing residential solar energy in a special heavy-concrete-weighted solar energy storage elevator is already available. The “overall energy” use for tall building elevators is very small ( just the cost of resistance and inefficiency ). No explosive hydrogen.

LOL duh but the majority of it in the US doesn’t Maybe you need to go back and check your sources for coal in the US. Not very many mountains being leveled for it. Some a big holes being dug though. Coal trains come from all over the US to Wyoming to get their coal. My dad lived in wyoming for a while and he visited that mine and related all the info to me. time for you to go back to school if you dont know about wyoming.

WHAT!? Coal has been found at the tops of mountains as well as at the bottom of the sea. Are you for real?
Ever hear of tectonics? Where are you getting your information, Wyoming?

Is there a way to not get so high temperatures? If we put a metal pipe with water for power generation I think is good that the lenses don’t melt down the pipe. I also wonder if the focus shape can be modified so not be a small square but a long line (for hit the pipe)?

Solar power rocks! All our energy really comes from the sun. Wind is coming from the sun. The power in oil is just trapped sunlight. So we know it must be able to cover all our energy needs.

I have reached over 5,000 F easily at the focus of the larger lenses. A small piece of steel at the focus spits and boils almost immediately (due to impurities and flaws in the metal structure).
We now have a functional power system made from 10 of the larger lenses. The volume of steam is nothing short of incredible. More video coming soon.

at 0:57 it is stated that 1.2 kW concentrated in 1 cm^2 means an energy density of 12 MW per cm^2. That is ridiculous. The energy density would be 1.2 kW/cm^2. where does that factor of 10,000 come from?
Educate yourself a little before making such claims.

Do you know of an sites with information on the new solar technologies, I agree that coal mining is not really low impact but I would rather bank on a easy and cheap source of power like nuclear.

Investors don’t agree. The new solar technologies work efficiently on overcast days as well as in full sun.
The fossil fuel cartels are fighting both solar & wind energy technologies tooth & nail for more than obvious reasons.
The government/corporate lobbyists against passive energy sources say they are concerned about the environment. As an environmental engineer I can say with certainty that fossils fuels are absolutely filthy, coal being the worst. (Levelling mountains: good ecology?)
