Wind Energy Residential
Cathy Said:
what does per kilowatt of energy producing capacity mean?We Answered:
It means exactly what it says, the cost of generation per kilowatt of energy produced. For example, a 50kW turbine may cost $50,000, which could be converted into $1 per kilowatt. A larger turbine, or a turbine farm may benefit from economy of scale and produce, say, 2MW and a cost of $1Million. Although the second option is more expensive ($1Milion vs. $50k), the cost per kilowatt is $0.50, which is a lot cheaper.Ted Said:
What is the best energy source for residential use Solar or Wind Power?We Answered:
A combination of both is best. especially if you are off grid, however both are nice if you are connected to the grid with an inverter, because pay back is quicker.Theideas has some very good points, I took for granted you have already figured out how much solar input you have, and basically you need more than 10mph average wind speed for turbines.
Kelly Said:
What degree would deal with renewable energy?We Answered:
Wind power: mechanical engineeringSolar power: applied physics - the technology for collecting solar power is still primitive enough that it's still physics, rather than engineering
Constance Said:
Why are wind turbines not invested more as an alternative energy source for residential homes?We Answered:
Some because you need the right conditions. Some because it's usually more expensive than just buying power from the electric company.Wind power is increasing all around the world, but the best way now seems to be large wind farms in the right places owned by the electric power companies and connected to the power grid.

Are we ever going to see incentives, in Canada, for applications of residental renewable energy usage?We Answered:

Anybody knows the price for a solar - PV and Thermal - system and the price of a micro wind power system?We Answered:
What should be a relatively straightforward answer, like it will cost you $14/watt for solar and $7/watt for wind power is not so easy in reality. There are "two" big challenges to understanding your PV and wind power system costs and power?#1. POWER IS HARD TO FIGURE OUT. You buy these systems based on their "nameplate" value, but you actually care about their total power generation:
To explain: Each of these systems, Solar or Wind, will be "rated" by their power production peak capability. This "rating" is known as their nameplate value, and when purchasing a "90 watt" solar panel, and the 90 watts is the peak power this panel can produce on a sunny day at noon. Similarly, a 1kW (nameplate) wind turbine will be "rated" for the peak power it can generate in fairly high wind (typically 30 mph sustained).
If you are actually using these systems for power generation, the nameplate value is good to know for the total power you will need to handle in the system, but not wholly useful for determining it's power production. What you actually care about is watts/per year, not watts per BEST CASE SCENARIO.
To determine your yearly estimated watts per solar or wind is quite hard and depends on your sun and wind conditions where you live and how you install these. In general, a solar system with nameplate power of 3 kW will produce approximately 4000 kW/hrs per year in "good" sun (southern U.S.), and a 3kW wind turbine will produce approximately 6000 kW/hrs in "good" wind (Wind class 3 areas.) A wind class map can be found at AWEA.org.
#2. PRICE IS HARD TO FIGURE OUT. Even if you do some math, and figure out your power production for your system, there is not an easy "price" total for either of these. Solar panels need installation, DC-AC inverters, grid-connection systems and/or battery systems. Wind systems also need installation, including potentially costly foundation and tower work if you want to get the turbine up into stronger winds, inverters, grid-connection and batteries etc. It is not atypical in EITHER solar or wind for the installed costs to double or triple the purchase of the panels or turbines themselves.
What you wanted to know was which to buy, the answer is: if it's really sunny and not windy, use solar, if it's windy (branches offer flutter on your trees), think about wind.
