Buildings account for nearly 40 percent* of total U.S. energy consumption and 70 percent* of all electricity consumption. As a result, buildings contribute to 39 percent* of overall carbon emissions in the U.S. In fact, the latest Intergovernmental Panel on Climate Change (IPCC) report cited that buildings provide the most significant opportunity for reducing carbon emissions.
Based on these numbers, they also play a significant role in the emerging energy questions of the near and long-term future of our economies and planet. Efficiency should always be the first consideration, and the development of renewable energy sources (i.e. wind, solar, tidal and micro-hydro) must be our next priority. These sources generate far less pollution and are perpetually regenerative.
Additionally, the uses of these sources on a distributed basis need to be explored. By generating electricity at the point of use, we eliminate the need for costly infrastructure while decreasing the amount of electricity that is lost during transmission. This strategy also minimizes the potential for blackouts due to natural disaster or other like events.
It’s still important to note that the playing field for these emerging technologies is not entirely level. Subsidies and tax breaks for older polluting fuels need to shift to renewable, distributed forms of generation.
People are ready to make a change, but in the current marketplace they don’t have access to the right choices. The recently signed stimulus package does include some relief to help get the renewable energy sector moving, but still doesn’t completely address the true opportunity that exists. Ultimately, significant changes must occur in coming years because our economy’s health and productivity depend on it.

Futura Solar thinks that the roof has to be the array and the array has to be the roof. EE & RE have to be at the heart of the system because turning off the internal electric lights (during the day) and eliminating the associated heat load will provice the greatest savings, which in turn will finance the transition. Gathering the solar load in any usable form then becomes the RE portion of the system. Thermal numbers are better than PV and routinely deliverable.

We need to quit subsidizing a non sustainable technology and send it back to the lab till the installed costs can be driven down to be competitive. Meanwhile look very seriously at cleaning up the heavy lifters of coal, ngas, and nuclear.
