These options may not supply the entirety of the power to the unit, but they are usually able to make a significant impact on cutting conventional energy costs, depending on the area. Naturally, in an area like the Pacific Northwest where it is usually cloudy or rainy, solar power would be less effective, and in an area where there is not much wind, wind power may not be justified on a cost basis. “Many energy providers say they have to charge more for renewables to offset the risk and expense of researching and developing new markets. "Providers say it is more expensive energy to produce, and its definitely true that wind and solar power have very small government subsidies compared to coal and nuclear power energy," says Isaac Elancavae of the Michigan Environmental Council” (Donner, 2002). As time passes, however, the cost of these options is dropping. Wind power does not create any sort of pollutant gases, as conventional power does.
These elements of wind power, pros and cons, will both be explored in more significant detail later in the report, but generally, these elements are used in tandem to create living and consumer spaces that are more environmentally friendly than they were in the past. For both materials and renewable energy resources, builders have virtually endless options. In terms of material, everything from insulation (recycled spray-insulation) to flooring (non-soil eroding bamboo floors) can be seen from a building green perspective. And in terms of renewable energy, as discussed above, although the main options are till solar and wind power, there are many other options also available to builders, such as methane and geo-thermal heat installation. Generally, as these technologies age, they become progressively cheaper. One may remember when buying a VCR cost several thousand dollars, when they were first invented. Today the same player costs under a hundred
