They're widely seen as stubborn. Willful. Obstinate, even. Guess what? They aren't. A study done by Canterbury Christ Church University and Devon's The Donkey Sanctuary showed that when it came to showing flexibility toward solving a problem (learning to learn), mules came out on top, ...
Solar panel efficiency varies widely based on the panel type, quality of manufacture and other factors like temperature. To calculate how many solar panels you need, you have to get specific about both your requirements and the electricity production capabilities of the photovoltaic module you’re...
Solar Water Heaters Solar water heaters use collector panels directly exposed to the sun’s rays to generate hot water for your home. The solar collectors use a heat transfer fluid such as ethylene glycol to capture thermal energy, which is then used to heat water for residential use. ...
northern United States receive a significant amount of solar radiation - more, in fact, than some countries such as Germany, Italy and Japan, where use of solar energy is becoming common; in particular, southern Alberta receives only slightly less than such "solar hotspots" as Arizona and ...

Peak sunlight hours vary widely by location, but a rough US average is around 5 hours a day. With the system outlined above and five hours of peak sunlight, you can expect to produce a minimum of 16kWh a day. 16kWh of electricity will recharge a Tesla Model X to almost 30% capacity...
almost anything that can be burned can be used as a fuel source, but to really work on a large scale, an alternate energy source has to meet certain criteria. It has to produce more net energy for less money than current technologies, it must be widely available in large quantities and ...
