Innovations: eFuel
With the never ending increase in gas prices, people have started to think about fuel alternatives. E-Fuel Corporation, a company in California, has introduced the EFuel 100 MicroFueler, a device that weighs about 200 pounds, that uses 110 or 220 volt power supply and a wastewater drain that is just like a washing machine. Using just water, raw sugar and yeast, consumers can create 100 percent ethanol at the push of a button.
Ethanol is a great alternative to gasoline; however, the MicroFueler costs close to $10,000 and requires a lot of electricity, water and sugar to create a sufficient amount of ethanol.
Thankfully, E-Fuel Corp hopes the changes in the North American Free Trade Agreement will allow the importation of inedible or “ethanol-grade” sugar from Mexico for as little as 2.5 cents a pound, thereby reducing the cost of making ethanol.
E-Fuel plans to distribute this device at the end of this year.
Where will Crude Oil Price end?
an exponential growth in Price of a barrel of Light Crude oil..
OPEC has seldom been effective at controlling prices. While often referred to as a cartel, OPEC does not satisfy the definition. One of the primary requirements is a mechanism to enforce member quotas. The old joke went something like this. What is the difference between OPEC and the Texas Railroad Commission? OPEC doesn't have any Texas Rangers! The only enforcement mechanism that has ever existed in OPEC was Saudi spare capacity.
As crude resources depleting in the world, and Mid eastern countries continue with Chaotic nature what will happen to supply of Crude Oil(CO)... This calls for greater need of alternative energy resources... As the CO demand increases today will the equilibrium price of CO continue to go up? I leave you today with these questions...

Wind Mill: power of wind
How a wind turbine works
Simply stated, a wind turbine works the opposite of a fan. Instead of using electricity to make wind, a turbine uses wind to make electricity.
The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity The electricity is sent through transmission and distribution lines to a substation, then on to homes, business and schools.
The advantages of wind power
The advantages of wind power are obvious: the energy is free and completely renewable, there are no hazardous emissions, and there are no adverse environmental impacts.
In 1990 in California alone, wind power offset the emission of more than 2.5 billion pounds of carbon dioxide and 15 million pounds of other pollutants - the same amount of air quality provided by more than 150 million trees.

Air conditioning your home
01. Maintain your central air conditioner by cleaning the outside compressor with a garden hose (be sure to shut off power at the fuse or breaker first). Keep plantings at least one foot away for adequate airflow.
02. During late afternoon and early evening, turn off unnecessary lights and wait to use heat-producing appliances. It's also a good idea to shade south- and west- facing windows during the hottest part of the day.
03. Plant a tree. One well-placed shade tree can reduce your cooling costs by 25 percent. For maximum benefit, place leafy shade trees to the south and west, and evergreens to the north.
04. Use ceiling fans to help circulate air throughout the house, and make sure your attic is properly ventilated. A ceiling fan should run clockwise during the summer, and counter-clockwise during the winter.
05. Set the fan on your central air conditioner to "on" rather than "auto." This will circulate air continuously, keeping the temperature more even throughout the house and aiding in dehumidification.
06. Make sure your window air conditioner is the proper size. It's better to get one that's too small than too large - a larger unit will start up and turn off more frequently and won't do as good a job dehumidifying the air.
07. Don't judge the efficiency of your air conditioner by the sound of the fan shutting on and off. The blower will continue to circulate cooled air throughout your home up to 15 minutes after the compressor has stopped. (The same holds true for the furnace.)
08. Raise the thermostat to about 78 to 80 degrees whenever you go to bed or leave the house. A programmable thermostat will do this for you automatically.
09. If your home can't accommodate central air conditioning, try a whole-house attic fan. This device pushes hot air out through attic vents, lowering the temperature throughout your home about five degrees in less than ten minutes. Attic fans cost less than 25 cents per day to operate.
10. During the winter, remove window air conditioners and seal the windows with caulk and weatherstripping. You might also want to cover the central air compressor with a tarp to keep it clean.

Electricity
Don't Heat - or Cool - the Great Outdoors!
Americans use twice as much energy as necessary to heat their homes. That accounts for a lot of wasted energy!
If you have a fireplace, close the damper when you don't have a fire burning. An open fireplace damper can let 8 percent of heat from your furnace escape through the chimney! In the summer, an open fireplace damper can let cool air escape. It's like having a window open!
Make a map of your home, and mark all the windows, heating vents, and outside doors. Take a ribbon and hold it up to the edges of the doors and windows. If the ribbon blows, you've found a leak! Ask Mom or Dad to seal the leak with caulk or weatherstripping.
Think about your curtains. Keeping the curtains closed on cold, cloudy days helps block the cold outside air from getting inside. Also, keeping the curtains closed on very hot days keeps the hot air out!
In the Bedroom
Turn off your electric blanket when you aren't in bed.
Don't leave on your computer, TVs, radios or games that use electricity when you're not using them.
In the Bathroom
Wasting water wastes electricity. Why? Because the biggest use of electricity in most cities is supplying water and cleaning it up after it's been used!
About 75 percent of the water we use in our homes is used in the bathroom. Unless you have a low flush toilet, for example, you use about five gallons to seven gallons of water with every flush! A leaky toilet can waste more than 10,000 gallons of water a year. Wow!
Drippy faucets are bad, too. A faucet that leaks enough water to fill a soda bottle every 30 minutes will waste 2,192 gallons of water a year.
Another simple way to save water AND energy is to take shorter showers. You'll use less hot water - and water heaters account for nearly 1/4 of your home's energy use.
In the Kitchen
According to researchers who are paid to study such things, a load of dishes cleaned in a dishwasher uses 37 percent less water than washing dishes by hand! However, if you fill up one side of the sink with soapy water and the other side with rinse water - and if you don't let the faucet run - you'll use half as much water as a dishwasher does. Doing the dishes this way can save enough water for a five-minute shower!
If you need to warm up or defrost small amounts of food, use a microwave instead of the stove to save energy. Microwave ovens use around 50 percent less energy than conventional ovens do. For large meals, however, the stove is usually more efficient. In the summer, using a microwave causes less heat in the kitchen, which saves money on air conditioning.
Don't keep the refrigerator door open any longer than you need to. Close it to keep the cold air inside! Also, make sure the door closes securely. There is a rubber-like seal around the door that you can test. Just close the door on a dollar bill, and then see how easy it is to pull out. If the dollar slides out easily, the door is probably leaking cold air from inside.
Is there an old refrigerator sitting in the garage or someplace else at home? Old refrigerators are real energy hogs! An old refrigerator could be costing your family as much as $120 a year to operate. Urge your parents to replace it if they don't need it, and remind them that one large refrigerator is cheaper to run than two smaller ones.
Don't Leave Things Turned On
Turn off the TV when no one is watching it. The same goes for computers, radios and stereos - if no one using it, turn it off. Turn off all the appliances at the surge protector/control strip - that four- or six-plug extension chord that you plug all your computer things into. Some devices, like modems or other networking boxes are drawing small amounts of power all the time. Check with your folks first, but the best thing to do is turn them ALL off at the surge protector.

Energy Efficient Bulb
Compact Fluorescent Lights (CFL) and Light Emitting Diode (LED) bulbs have revolutionized energy-efficient lighting.
CFLs are simply miniature versions of full-sized fluorescents. They screw into standard lamp sockets, and give off light that looks just like the common incandescent bulbs - not like the fluorescent lighting we associate with factories and schools.
LEDs are small, solid light bulbs which are extremely energy-efficient. New LED bulbs are grouped in clusters with diffuser lenses which have broadened the applications for LED use in the home.
Benefits
Efficient: CFLs are four times more efficient and last up to 10 times longer than incandescents. A 22 watt CFL has about the same light output as a 100 watt incandescent. CFLs use 50 - 80% less energy than incandescents.
Less Expensive: Although initially more expensive, you save money in the long run because CFLs use 1/3 the electricity and last up to 10 times as long as incandescents. A single 18 watt CFL used in place of a 75 watt incandescent will save about 570 kWh over its lifetime. At 8 cents per kWh, that equates to a $45 savings.
Reduces Air and Water Pollution: Replacing a single incandescent bulb with a CFL will keep a half-ton of CO2 out of the atmosphere over the life of the bulb. If everyone in the U.S. used energy-efficient lighting, we could retire 90 average size power plants. Saving electricity reduces CO2 emissions, sulfur oxide and high-level nuclear waste.
High-Quality Light: Newer CFLs give a warm, inviting light instead of the "cool white" light of older fluorescents. They use rare earth phosphors for excellent color and warmth. New electronically ballasted CFLs don't flicker or hum.
Versatile: CFLs can be applied nearly anywhere that incandescent lights are used. Energy-efficient CFLs can be used in recessed fixtures, table lamps, track lighting, ceiling fixtures and porchlights. 3-way CFLs are also now available for lamps with 3-way settings. Dimmable CFLs are also available for lights using a dimmer switch.

Reusable Bags for Grocery Shopping
The new Wal-Mart shopping bags are made from a fabric containing rPET. The bags are made from 85% recycled content and hold more than twice the amount of an average plastic bag. The bags are sold for $1 and be located near checkout aisles in Wal-Mart stores. Wal-Mart also take the bags back at the end of their life-span for recycling. Give it a shot next time you go grocery shopping.. you will be surprised how many small things you can put in that Black reusable bag.
Carbon Sequestration using trees
Carbon dioxide is a potent greenhouse gas and a major contributor to climate change. Carbon Sequestrating indicate storing carbon in trees which are then turned into Organic Carbon through photosynthesis. This carbon is also stored in plant tissues. Thus furniture made from wood store carbon for a long time.
There are three types of Sequestration,
1. Biological Sequestration
2. Geological Sequestration
3. Ocean Sequestration
Carbon intake has been estimated and below are some quantitative data which can give a clear idea of how effective this can be.
25 year old deciduous tree – sequesters 2.52 lbs of CO2 annually
120 year old deciduous tree – sequesters 5.58 lbs of CO2 annually
25 year old evergreen tree – sequesters 14 lbs CO2 annually
120 year old evergreen tree – sequesters 11.7 lbs CO2 annually
(Figures generated by Tufts (University) Climate Initiative)
Some people believe planting trees just for the purpose of Sequestration could reduce the amount of CO2 in the atmosphere. But an article published in Duke University says, the Carbon Sequ. can cause water and nutrient depletion and increased soil salinity and acidity as side effects over decades. Read more about this.
But that doesnt mean we should stop planting trees. Planting trees as much as we can will help us reduce Carbon levels and delay the changes in Climate if not change it back to before...
