One idea is that a sewage treatment plant could use the energy created by the waste it processes to process more waste; in other words, a closed-loop operation with zero net energy and zero residuals.
Scientists and engineers recently made a leap forward in the pursuit of clean energy. The team set a new world record for plasma pressure which is the key ingredient to producing energy from nuclear fusion, and MIT
Garden grass could become a source of cheap and clean renewable energy, scientists have claimed. A team of UK researchers have shown that significant amounts of hydrogen can be unlocked from fescue grass with the help of sunlight and a cheap catalyst.
An international team of scientists has come up with a new type of energy system they're calling 'hydricity', which combines the power of sunlight with hydrogen fuel.
