The company captures the biogas from cow manure and converts it into usable energy.
It is energy dense, it carries in a small volume a lot of usable energy.
As a result, palm oil uses significantly less land to generate the same amount of usable energy.
Biofuel made from these sources provide two to three times the amount of usable energy required to produce it.
Within those batteries Audi estimates that "26.5kWh of usable energy at 380 volts" can be stored, allowing for a maximum range of about 92 miles.
An average of 97 percent of waste products are either reused or recycled at these 76 facilities with an additional three percent converted to usable energy.
Nanophosphate EXT is based on A123's proprietary lithium iron phosphate battery technology, which offers high power, long cycle life, increased usable energy and excellent safety as compared to other available battery technologies.

For example, microchips will be a major component in renewable resource technology such as solar panels, helping make the collection of solar power and the subsequent production of usable energy as efficient as possible.
The silver cylinder at the top is actually a small power generating device that converts micro-vibrations into usable energy, so stick one of these on, say, a ventilation duct and you should just about get enough juice to power a calculator or even an LED.

Amin Karami, an aerospace engineering research fellow, presented data at the American Heart Association annual conference in November showing an experimental energy harvester can convert the energy from the beating of a heart into enough usable electrical energy to, in theory, operate a pacemaker.
Japan Nuclear Fuel's Mr. Fukushi stressed that the United Nations' nuclear watchdog, the International Atomic Energy Agency, will closely monitor Rokkasho's operation to guard against potential diversion of the weapons-usable plutonium.
