How to save Money With Green Electricity
Green Electricity - Cost Savings From Residential Wind Turbines How Much Green Electricity And Money Savings Can I Expect From A Wind Turbine? This article provides you with detailed information about how much green electricity wind turbines can produce and the $ savings which can be achieved.
GENERAL WIND POWER INFO: As a thumb of rules, for every doubling in wind speed, the energy available from the wind increases approximately eightfold. Therefore, the more exposed your site is and the greater the average wind speed obtainable at your site, the greater the potential for harnessing power from the wind. Furthermore, wind speed increases with height whilst at the same time turbulence reduces, providing more reliable and consistent power output and a safer operating environment for the turbine.
ELECTRICITY GENERATION: Well sited wind turbines can expect to produce energy equivalent to their rated power for around 30% of the year. Here a few examples based on this conversion rate: A turbine rated at 4Kw: (4kW x 0.3 x 8760 hours in a year) = 10,512 kWh per year. A turbine rated at 5Kw: (5kW x 0.3 x 8760 hours in a year) = 13,140 kWh per year. A turbine rated at 10Kw: (10kW x 0.3 x 8760 hours in a year) = 26,280 kWh per year. A turbine rated at 20Kw: (20kW x 0.3 x 8760 hours in a year) = 52,560 kWh per year. If you your site is exposed to wind which produces a higher conversion rate to lets say 40% or 50% of the year, then simply use the above formula and apply the equivalent denominator i.e multiply by 0.4 or 0.5 etc.
ELECTRICITY CONSUMPTION: To give you an idea of the watt consumption of standard household electrical equipment, below is a table showing a few examples. You can always obtain the exact watt rate of any of your equipment used at home (fridge, dishwasher, tumble dryer etc.) from the technical label usually attached at the back of the equipment. Medium unit Window AC 1000 Wattts one hour 1kWh Large unit Window AC 1500 Watts one hour 1.5kWh Light Bulb 100 Watts 730 hours 73kWh ELECTRICITY COSTS: The average cost of residential electricity was 11/kWh in the U.S. in December 2008. The average US household uses approx. 936 kWh/mo. and would pay about $100 for it based on this average average rate. But to make sure to get your calculations right, please note that the cost of electricity depends very much on where you live, how much you use, and possibly when you use it.
