Have you thought of using geothermal to heat your house? It is a very clean way to do so. It emits almost no green house gasses. The way it works is when groundwater seeps below the Earth's surface near a dormant volcano, it is then heated by reservoirs of molten rock. That is usually at depths of up to 9,800 feet below the Earth's surface. To get this water they have to drill down for it. They take it to a plant where they separate the steam and the hot water. The steam is cleaned and sent away and the water is sent back down into the ground where the process can be started all over again.

Cow Manure for Energy
Kyra and Noelle
For our science fair project we are using cow and horse manure to make energy. What we are doing is mixing cow manure with water and putting it into a bottle. Next we will run a tube out of the top of the bottle into another bottle. We then put the tube at the top so that the gas goes into the tube and into the other bottle. The other bottle has another jar inside of it. The bottle is halfway filled with water. When the gas comes into the bottle it goes into the jar and the gas pushes the water out. When all the water is out of the jar that means that the jar is filled with methane gas. From there we are going to see how much gas we can get out of cow manure and horse manure. So we will use a Bunsen burner to measure how much gas we get and what color the flame is. To get the gas into the burner we will have a T in the tubes so that we can turn a valve and have the gas come out into the Bunsen burner tube. When we light the burner we then time how long the flame lasts and what color the flame is. When we do this the first time we empty it out the jarand do not use the gas because it will mostly be CO2. We will then repeat this 2 or 3 times to test the gas.

New form of gas?

Studies show that water can replace gas as automobile fuel. How is this possible? Water contains a substance that, combined with baking soda, becomes almost as combustible as gas. Almost. This form of energy is nearly limitless because, after a day or two, it's back to normal water. Add more baking soda and voila. The reason for the baking soda is that it pulls out the combustible substance. Baking soda water won't explode but the vapor it puts off will. Put that vapor in with gas and you can get 5 extra miles with every tank depending on how big it is.

Presidential Plans
Posted by TylerPresident-Elect Barack Obama, and Vice President-Elect Joe Biden, have some major plans to change the reliance we have on foreign oil. As well as new renewable energy for example...
- Put 1 million Plug-In Hybrid cars - cars that can get up to 150 miles per gallon - on the road by 2015, cars that we will work to make sure are built here in America
- Ensure 10 percent of our electricity comes from renewable sources by 2012, and 25 percent by 2025.
- Implement an economy-wide cap-and-trade program to reduce greenhouse gas emissions 80 percent by 2025.
- Provide short-term relief to American families facing pain at the pump
- Help create five million new jobs by strategically investing $150 billion over the next ten years to catalyze private efforst to build a clean energy future.
- Within 10 years save more oil than we currently import from the Middle East and Venezuela combined.
- Barack Obama and Joe Biden: New energy for America
While most of Obama's plan is based on environmental safety "making U.S. leader in climate change", reducing independence on foreign oil, and creating fuel efficient cars... I'm sure if he looked at this blog he could find other sources... But on bullet 2 Obama mentions renewable energy. What exactly does he have in mind? Looking at the Obama Biden websight (link at bottom of blog) he outlines his plan for renewable energy, which includes "Clean Coal Energy" and "Safe and Secure Nuclear Energy"
Don't forget to watch the movie of former U.S. Secretary of Commerce, Robert Mosbacher Sr.
Here are some great sights explaining the possibilities these sources present.
Besides Nuclear Hydro-electric energy is resource capable of creating large amounts of electricity without forming harmful gases harming the ozone.
Obama's plan is, at least, a plan and in this time that's what we need.
Biochar

Biochar is a charcoal produced from biomass that can store carbon. It is of increasing interest because of concerns about global warming caused by emissions of CO2 and other greenhouse gases.
In some cases, the term is used specifically to mean biomass charcoal produced via pyrolysis. Biochar may be an immediate solution to reducing the global impact of farming (and in reducing the impact from all agricultural waste). The burning and decomposition of trees and agricultural matter contributes a large amount of CO2 to the atmosphere and greatly impacts global climate change.
Biochar can store this CO2 in the ground and the presence of the biochar in the earth increases soil productivity, which will allow farmers to stop encroaching on rainforests as a source of more fertile farmland. As a result of significant product variations due to varying technology, process conditions, and feedstock compositions, biochar can not be considered a commodity product. Biochar is sold under a range of brand names such as the well-known global brand name and US registered trademark Agrichar™ which relates to Biochar produced from the BEST Energies proprietary slow pyrolysis process.
