Question by ny_spinner_dan: Why aren’t geothermal energy sources more prominent?
I am doing a presentation on geothermal energy, and all the information that I am finding on them is extremely posetive. They seem to be very eco-friendly, very energy efficient, and long-lasting.
Why then are they used so infrequently?
Best answer:
Answer by poiromaniacthey are very hard to retro fit, (put in after the build) as they have to be piled into the ground (obv) but also new builds are keeping prices down so unless you are designing the project yourself there is often lil chance of being offered the geo option.

Energy Efficient Microwave Systems: Materials Processing Technologies for Avionic, Mobility and Environmental Applications
Many individual technological solutions for microwave applications in industries have been developed without a clear pattern for a key strategy to replace conventional industrial technologies. In this work, the author shows how a modular microwave system line for very homogenous microwave fields is originated. “Energy Efficient Microwave Technologies” is designed for engineers and scientists from industry and academic research. The number of applications of this new technology is enormous: In th

Question by pink.love: I know fluorescent lighting is more energy efficient but how much energy is it saving?
What if all the fluorescent lights in a classroom were turned off, about how much money or energy would that actually save?
Best answer:
Answer by Jerry LeeIt will depend on the size of the classroom, and how well lit it is. It will require more lighting if it has dark paint or dark floors, or faces north, or they have classes at night, or there are no windows at all.
I estimate 1,000-2,000 Watts.
