In a certain sense yes, because cogeneration recovers heat that is usually lost.
Conventional gen-sets and power plants have a global efficiency of 30 - 40 %, meaning that 60 - 70 % of the fuel is wasted as heat dumped in the environment. Cogeneration (also called Combined Heat and Power or CHP) consists in using this heat instead of dumping it. But since heat is harder to move than power, cogeneration is possible only if power is produced locally, at the building. Thanks to cogeneration, more than 90 % of the fuel can be used, which considerably reduces consumption, and consequently operating cost and carbon emission.
Biofuels are the various fuels produced from biological processes, like agriculture and waste treatment. They have numerous advantages over fossil fuels, in particular they produce much less GHG (glasshouse gases). Biofuels are a sustainable solution of world energy problems, in that they are renewable (they are actually solar energy stored in chemical form), economical (their final cost is nearly that of fossil fuels with taxes) and very abundant. Contrary to what many people think, our planet has largely enough area to produce all its energy from biofuels without compromising food supply.
A flywheel stores energy as "kinetic
energy", which is the energy of a moving
mass. For instance, a moving car has a certain
amount of kinetic energy, as it may cover some
distance freewheel with its engine idle. The
ENERGIESTRO set stores energy by spinning its
flywheel.
The first model, with 6 kW power rating, has begun tests in pilot sites in 2011.
