stop wasting money on photovoltaic

Don't get me wrong, PV has its place, but it is one of the least efficient conversions of solar energy.

Most building HVAC air displacement could be achieved by solar thermal convection. Most buildings hot water needs could be met by solar thermal, and create more energy through savings that could be created by PV in ten times the space. Many buildings could get significant winter heating from trombe walls or similar... more »

Turn Federal Building Rooftops into Solar Collectors

My suggestion is for every federal building to allocate 20%-30% of its rooftop space for solar energy. Solar cells would be tied into the grids of DC electric companies. As electricity is generated, meters would automatically move backwards saving the federal government money, enough to offset the cost of this equipment within 5-years or less (especially on weekends, when little or no staff is present).

Solar Power

I work in the IRS Campus in Holtsville, NY. There are about 3000 employees in four attached buildings with flat roofs. If we were to convert to Solar Power, not only would it save millions of dollars and help the environment, it may actually generate revenue because of the vast area exposed to sun. The govt, state and local agengies all have financial incentives including the town of Brookhaven which is eliminating the... more »

Shining a Light on Energy Production

Turn large numbers of exposed roofs on public buildings, such as schools, libraries, etc... into solar energy farms to generate electricity for use in their missions to educate our children and the community, while providing the national grid with any energy produced beyond their requirements.

 

This concept works in harmony with several national education standards and opportunities for citizen scientist engagement.

Solar Street Lights

I think that if every streetlight on federal highways, roads and installations should run primarily on a solar cell that charges by day and can run for 14 hours, per charge. Then, there would be no need to have them on the power grid, which will limit the amount of energy constraints on the system. This will lower the cost of production of energy and help distribute it to other places.

Use Solar and Wind Energy At Large Posts of Duty

Use wind and solar energy generation as much as possible in large campuses. It should be possible to set up at least one windmill in each large post of duty where there are more than 800 employees. Solar panels can be placed on lawns or rooftops. Don't try to provide for all the electrical usage, but rather try to replace as much conventionally generated electricity as possible with wind or solar-sourced energy at the... more »

SOLAR DAYS: TURN OFF THE LIGHTS

Turn Off the Lights! This is a very simple principle. Savings would be evident even if we opted to assign one day each week as a "Solar" only day. Frankly, we can use sunlight to accomplish our many tasks throughout the day. So in addition to energy efficient lighting, we can definitely go the extra mile to simply turn off the lights. Now, doesn't "Solar Mondays" have a nice ring to it? Preferably, we should turn off... more »

Recharging Alkaline Batteries is Possible using Solar

I suggest you try and recycle alkaline batteries using the following method. My husband did this at home quite by accident, and it works fantastically for AA alkaline batteries. We have found that we can recharge and recycle alkaline batteries by putting them into our solar outdoor lighting systems instead of the expensive "solar" batteries. I guess the trickle charge is low enough and long enough to perform the job.... more »

Solar Power and Eco-friendly facilites and equipment

We could save millions of dollars in costs just by building better facilities and improving existing facilities and equipment to be more eco-friendly. Currently the El Paso Border Patrol station is an example of the improvements that can be made in this area by using eco-friendly materials as well as solar power which currently supplies almost 20 % of the stations power needs. By utilizing solar power for facilities... more »
