Q&A: WHAT SOLAR PANEL EFFICIENCY WOULD REPLACE COAL?
May 17th
Question by elrodvoss:
What Solar Panel Efficiency would replace Coal?
A friend sent me an article that a company called Fraunhofer has produced solar panels that can achieve 41.1% efficiency.
Now taking into account the fact that solar do sent work during storms or night and greatly reduced during winters, what % do you think would be needed to supply a “majority” of our power needs as a nation?

WOULD ADDING WIND TURBINES AND SOLAR PANELS TO UTILITY POLES BE FEASIBLE TO REPLACE CURRENT ELECTRICITY?
May 24th
Question by Alice In Wonderland:
Would adding wind turbines and solar panels to utility poles be feasible to replace current electricity?
We already have utility poles and the wires and such. Why could not we just add a wind turbine , solar panels, converter and battery and just convert the whole system. Instead of living off grid, we change the grid. But my research is frustrating me. I need to know if it could possibly work.

REPLACE REGULAR LIGHT BULBS WITH ENERGY SAVING?
Apr 9th
Question by secondwish02:
Replace regular light bulbs with energy saving?
If each American home replaced just one light bulb with an ENERGY STAR fluorescent bulb, we would save enough energy to light more than 2.5 million homes for a year and prevent greenhouse gases equivalent to the emissions of almost 800,000 cars.
Have you replaced the regular light bulbs in your home, and if so, how many have you replaced?
