Wind and Coal...Two Sources Used for Creating Electricity
Written by Mohammad Aljanah and edited by Kimala Dhillon
Coal is a fossil fuel that has been formed from the organic remains of prehistoric plants and animals.Fossil fuels provides about 66% of the world's electrical power, and 95% of the world's total energy demands that includes heat, transportation and electricity generation.In order to create electricity using coal, the coal first has to be crushed into a fine dust, which is than used as fuel to heat water. The steam generated in this process is used to turn turbines in generators that create electricity.
Wind is air movement, which is created by the sun heating the spinning earth, and creating different air temperatures in the atmosphere that cause movement of the air.Wind has been used throughout the ages, including the Babylonian period (1696 – 1600 BC) and the Middle Ages. Windmills were used to grind corn and to pump water to dry lands to irrigate crops.
3KW-30KW Medium to Large residential turbine systems - from $8,000.00 USD
30KW-150KW large residential/commercial Systems - from $52,000.00 USD
150KW -3000KW or higher - Industrial Turbine Systems - from $300,000.00USDAerodynamic designs have improved modern wind farms and are much quieter, a lot quieter than a fossil fuel power station.

- Most power stations are located on the coast, using seawater as a cooling system. However, this will raise the water temperature of the sea effecting the environment.
- Burning coal produces sulfur dioxide (a strong smelling toxic gas) that contributes to the creation of acid rain. Carbon dioxide contributes to the "greenhouse effect” and “global warming”.
- The nature of mining coal is extremely dangerous and destroys large areas of the environment.

- Noise of generated by the propellers and gear box. A wind generator makes a constant, low, "swooshing" 24/7.
- Unpredictability – windy days to no wind at all.
- Cost of land near the coast, which is suitable for wind farms.
- Minimum wind speed required is 25km/h, which means endangering birds and migrating flocks. Birds tend to favor strong winds.
- Effects broadcast reception nearby.

Comparing Heating Fuels

When selecting the fuel and heating system best suited for your needs here are some factors to consider.
These include:
When selecting the fuel and heating system best suited for your needs here are some factors to consider.
These include:
- Cost and availability of the fuel or energy source
- Type of appliance used to convert that fuel to heat
- How the heat is distributed in your home
- Cost to purchase, install, and maintain the heating appliance
- Efficiency of heating appliance and delivery system
- Environmental impacts associated with the heating fuel
Gasoline, Diesel, and the Future Sustainability of Auto Fuels
by Kimala Dhillon
When choosing between gasoline and diesel for transportation, consumer cost as well as environmental cost needs to be considered. With energy needs and fuel prices rising, and the worldwide supplies of oil declining, sustainability requires alternative options such as renewable energy sources.The national average for gasoline during the week of November 9, 2009 was $2.67 per US gallon, during that same period diesel averaged $2.80 per gallon. While that makes gas look like the consumer bargain, in actuality diesel contains more energy per gallon than gasoline. Diesel contains 129,500 BTUs per gallon versus only 114,000 BTUs for gasoline. (BTU stands for British thermal unit, which is a unit of energy used in the US.) Because diesel contains more energy per gallon than gasoline, it causes more greenhouse gas emissions per gallon. However, due to the better mileage when compared to gasoline, diesel engines emit up to 20 percent less greenhouse gas per mile than comparable gasoline engines.
One disadvantage of the diesel engine is that it produces soot, which consists of solid carbon compounds that have been left unburned. The problem is worsened during cooler weather, because diesel fuel burns less efficiently at colder temperatures or while the engine block is cold at start up. Exposure to soot can have adverse health effects such as headache, nausea, coughing or difficulty breathing. Continuing exposure may lead to cardiovascular disease as well as lung cancer. Stricter federal emission standards that will become mandatory in 2010 will require more refining of diesel fuel so that it produces less soot when burned, which may add to consumer cost. Gasoline is more volatile than diesel (meaning it evaporates quickly). It is even more volatile in hot weather, and unlike diesel can easily ignite in such conditions. Gasoline also contains many known carcinogens. Gasoline leaks therefore are an ongoing public health concern, but because of the well-developed nature of the industry, there are safety practices in place to prevent large scale or ongoing leaks that might compromise drinking water. Unburned hydrocarbons from gasoline produce photochemical smog. Federal volatility limits reduce the emission of unburned hydrocarbons. Controls on automobiles limit the release of hydrocarbons by collecting expanding fuel vapor while the engine is shut down and directing it for use later when the engine is running.
Although gasoline and diesel, infrastructures are well established, there are ever-increasing alternatives to these options. Two of these alternatives require little if any infrastructure changes. I think the more interesting of the two is biogasoline (bio-petrol), yes a renewable petroleum product, which can be used in conventional gasoline engines. What is equally compelling is that, because of the similarities of gasoline and biogasoline, the fueling infrastructure in place already is able to distribute the newer product without costly changes.
Apparently, acids normally excreted by industrial yeast or nonpathogenic E. coli are only a few molecular stage removed from crude oil. By altering the microorganisms DNA, a process that now only takes weeks and is relatively inexpensive, they excrete renewable petroleum, while feeding on agricultural waste. This product requires much less refining than does traditional crude oil, which uses an energy intensive process. Additionally on an environmental note, the process of manufacture is carbon negative, consuming greenhouse gasses rather than emitting them. Depending on manufacturing procedures, biogasoline is able to operate at lower than normal temperatures and can contain a greater octane level, which is better for your car engine. Theoretically, biogasoline could end our dependence on foreign oil, while reducing the cost of gasoline and because the product is interchangeable with crude oil, a re-engineering of the global infrastructure is unnecessary. In the fight for sustainability a few companies are working on developing synthetic gasoline, LS9 is one such company. LS9 will have a scale plant operating in 2010, while designing a commercial facility to open in 2011.
Bio-diesel is the other fuel alternative that I want to discuss, it can be made from either vegetable or animal fats, and is used in standard diesel engines making it different from the vegetable and waste oils used in converted diesel engines. It is made from glycerin that has been removed from oil molecules, which thins the molecule. Biodiesel has a much higher octane rating than current diesel fuels and has virtually no sulfur content. In lower temperatures, bio-diesel can thicken in the fuel system. Biodiesel may help decrease our energy footprint and decrease our dependence on foreign energy.
The importance of the current energy infrastructure cannot be minimized when considering consumer cost, but at the same time sustainability, requires alternative solutions to finite fossil fuels. While the renewable gasoline and diesel options discussed conform well to already well established fuel infrastructures worldwide they also lower consumer costs, are better for the environment and reduce our dependency on foreign energy sources.
