This is the fifth in a series of video podcasts for the PBS series e2 energy. Each podcast takes you beyond the episodes and deeper into the world of alternative energy. This podcast explores a process called "carbon sequestration" which may one day allow the United States and other countries to burn abundant coal reserves without emitting greenhouse gases. But the technology is far from complete, and some skeptics question its ability to effectively capture carbon dioxide. Learn more about the carbon capture process from leading researchers in the field. e2 is an ongoing documentary series about the economies of being environmentally conscious.

I'm about to build a homemade power source and was considering solar cells and fans (air), anyway.

Solar cells are expensive and don't really generate that much power. The area will be about 30 cm2. I've seen that It's possible to build your own solar cells but they generate very little electricity.

So what can I use instead of solar cells (for sun light or uv rays)? Is there some way to create more powerful solar cells at home instead of buying? How?

P.s. this is for a project in school, so I need cheap and effective solutions.

Thanks!

The Orion Project is a non-profit foundation created to transform the current energy, environmental and social crisis into a world of sustainability and enlightened abundance. In this video, project director Steven M. Greer, MD, answers the question: "How have these alternative energy technologies been suppressed?" www.TheOrionProject.org ... grassroots outreach nonprofit Steven Greer alternative energy research environment Tesla zero point

So I'm reading this article on Wikipedia about Solar Energy. I have to do this project about biofuels, and solar energy is one of them. It says:

"Solar technologies are broadly characterized as either passive or active depending on the way they capture, convert and distribute sunlight. Active solar techniques use photovoltaic panels, pumps, and fans to convert sunlight into useful outputs. Passive solar techniques include selecting materials with favorable thermal properties, designing spaces that naturally circulate air, and referencing the position of a building to the Sun. Active solar technologies increase the supply of energy and are considered supply side technologies, while passive solar technologies reduce the need for alternate resources and are generally considered demand side technologies."

I don't understand what they mean. Do active thinger-majiggers move toward the sun, and passive ones just sit there and absorb the sunlight?

Forget the axis of evil, its the axis of oil The Cold War and the War on Terror were about ideology and globalization. The 21st century will be dominated by the struggle for energy: It will be every man for himself and it's going to get dirty. In the two-part documentary Energy War, vpro's Backlight investigates the major developments with regards to energy sources. Featuring NY Times columnist Thomas Friedman. The film describes the geopolitical consequences of the dependency on fossil fuels. In the struggle for the last sources of fossil fuels, countries all over the world are forced to take new political and moral decisions and have to enter into awkward alliances: rogue regimes must be tolerated and befriended. With a special focus on the gas conflict between Georgia and Russia and the position of Saudi Arabia. Featuring ao Thomas Friedman, author of international bestseller The World is Flat. Friedman sheds his light on the inverse connection between rising oil prices and the establishment of free democracies. The film then moves on to take a look at the international markets for alternative energy. If oil and gas are scarce and expensive in the future, where will countries turn to keep their economy going and their population warm and happy? Could solar energy or bio fuels become the main energy sources of the post-fossil fuel era? Will governments, multinationals or small producers be the motor of the green race?

I have a report due tomorrow... I need to define and describe the following alternate energy types:
solar, geothermal, hydro, wind, hydrogen, and biomass.

How do you think energy resources affected the campaign for presidency? What are Obama's views on alternate energy resources?

Please answer as best as you can! XD

Thanks soo much! ?

If you're searching for websites on an alternative energy solar panel, then you definitely need to read this quick article - it is going to radically change your current thinking about the latest in the field of solar energy. What if you were to learn that the technology now exists which provides you the simple technology for converting solar energy into abundant energy for your home at a budget you can easily afford - wouldn't you be eager to learn more? Keep reading the following article.

In the recent past, taking the leap into solar-generated power for your home electricity was seen as an undertaking that was out of the reach of most people, while many hoped that one day it would become more accessible. You are one of many thousands who search the web for an alternative energy solar panel, which is evidence that interest in solar energy is expanding, and there are many looking for ways to get started in the realm of solar energy.

The latest word in this fast-growing field is that the latest technology is now available and is no longer expensive. now anyone can get up and running with as much free electricity as you need, and then some. This technology has been around for a long time, but few people had the money to invest in getting set up with it; unfortunately we had to keep getting our power supply from the power company, wasting hard-earned money on a basic need.

Before going on with your search for information on an alternative energy solar panel, It's important to learn about a recent advancement in this area: a respected professional in the field of green technology wants to expand the use of green energy by showing you how to construct solar panels and a solar energy system of your very own, by utilizing materials that are both inexpensive and readily available anywhere. I realized that there happen to be a large quantity of people in the u.s. and around the world, who already use solar power to generate their own supply of clean, green energy, and even generate extra income by selling unused power they've generated to the power company. As it has now become the common-sense solution, homemade energy production is going to create a much-needed revolution in the entire energy industry.
