ROI is all over the place … what is that actually mean ? It’s like a low yield bond, you’ll make a return but if you had just continued living on the grid for another couple of years and then … Continue reading →

there isn’t a good way at home. on a very large scale, there was a double reservoir that generated electricity as water flowed from the upper to the lower sections, and when there was excess capacity, it pumped water from … Continue reading →

1) Suppose that you want to erect a 3 Kilowatt [peak energy output in a strong wind] wind turbine. Assume that the site is located in an area rated in top 20% for annualized wind energy potential [in an inhabited … Continue reading →

Solar plates? Solar collector? Photovoltaic cells? You have 3 good answers right in your question. Through tools such as those, solar power is harvested, and to take it a step further, storage by batteries would be a way to keep … Continue reading →

Which of the following would be a feature included in a home being built using passive solar energy features? a. tile floors b. photovoltaic cells c. solar panels d. natural gas furnace a. tile floors to absorb day time sun/heat

I’m writing this essay and i need to make a table so i can make a graph but does anybody know what i can compare? i had a table of the comparison of solar panels to wind turbines but my … Continue reading →

I m considering this field for master’s degree I mean i find that it will be a recommended field more and more in the future but i m afraid that it might be narrow To be specific,i m want to … Continue reading →

. The amount of sunshine on a horizontal surface at the equator is 5kWh/m2/day. Suppose this house is to run entirely off grid on solar electricity alone using a high performance silicon photovoltaic module with specifications shown below: Maximum power … Continue reading →

I need some help. I am looking for cheap ways to get solar energy, possibly built it yourself solar panels, or cheap commercial options… This site is amazing

Apart from photovoltaic (solar) cells how do we use solar energy? The sun makes the wind blow (warm air rises and the wind is air filling the gap left) so sun power drives windmills, wind turbines and sailing ships. The … Continue reading →
