An irreversible process is one in which energy is dissipated (spread) into empty energy states available in a volume, from which it cannot be recovered into more concentrated forms (fewer quantum states), without degradation of even more energy. A reversible process is one in which this sort of dissipation does not happen. For example ...
2. Squeeze in More Physical Activity. It can feel like a catch-22. When you’re low on energy, the last thing you want to do is hit the gym. But regular exercise can actually help reduce feelings ...
Hydroelectric power can supply 1/3 of our total energy global needs. Geothermal energy can provide 1.5 more times the energy we need. There is enough wind to power all of humanity's needs 30 times over. Solar currently supplies only 0.1% of our world energy needs, but could power humanity's needs 4,000 times over, the entire global projected ...

If you read my recent article, you know I'm not the biggest fan of electric vehicles and their long-term viability. Not only are there issues with the current batteries being used, but there are ...
Light: Energy produced by light being absorbed by photoelectric cells, or solar power. Chemical: Energy produced by chemical reaction in a voltaic cell, such as an electric battery. Pressure: Energy produced by compressing or decompressing specific crystals. Magnetism: Energy produced in a conductor that cuts or is cut by magnetic lines of ...
In 2019, another Brazilian tailings dam (owned by one of the same companies as the dam that collapsed in 2015) ... 'Clean' energy still needs mining, but there's a smarter way to do it. Show comments.
Renewable energy (or green energy) is energy from renewable natural resources that are replenished on a human timescale. The most widely used renewable energy types are solar energy , wind power , and hydropower .
