A hydropower facility consists of a plant for electricity production and a water reservoir formed by a dam in a river. The dam has gates that can open or close depending on how much water is needed to produce a certain amount of electricity. The electricity is transported thr...
Fuel-cell cars sound promising, but if battery cars really are better, hydrogen may turn out to be an expensive distraction from the important business of switching the world from fossil fuels to renewable energy. All these problems, summed up, explain why battery-car advocates like Tesla's ...

increasing the CO2levels in a planet's atmosphere, causing rapid heatingThis is a reference toclimate changecurrently occurring on planet Earth. Theoverwhelming consensus among climate scientistsis that this is that this shift is caused by human factors, such as the burning of fossil fuels releasing...
How does a nuclear power plant work? Okay, we've figured how to get energy from an atom, but the energy we've got isn't that helpful: it's just a huge amount of heat! How do we turn that into something much more useful, namely electricity? A nuclear power plant works pretty much...
From the perspective of psychology, framing is best understood as different ways in which information is presented [97] with a potential impact on how information is processed, and preferences are formed. The frames will focus on specific aspects and exclude or minimize other relevant aspects of ...
