That can lead to higher maintenance costs and lower energy yields than expected.

It will, however, be necessary to keep a close eye on the overall energy yield of biomass.

These modules are particularly powerful with high quality, reliability and good energy yield.

They'll give you higher density and the best kinetic energy yield.

Aluminium is typically added to explosives to increase their energy yield.

Its energy yield was directed at the developing oil field in the Ponath.

Typically they will produce a higher energy yield with the same effective absorber area.

The main advantage of Nuclear power is that it requires significantly less fuel and therefore has a much greater energy yield.

"At present, the two techniques have low energy yields.

Long-term energy yield may be affected by climate change.

Most of the research is targeted at improving efficiency and increasing overall energy yields.

One can calculate the energy yield - actually, just an upper bound, which turns out to be considerable.

There are, however, a number of minor opportunities for production technique development in order to improve energy yield efficiency.

Even within a single zone the energy yield can differ by up to 13% depending on the location chosen for development.

In Primary devices a high energy yield is produced through fissions of heavy elements.

This has an annual energy yield of some 53,000 kWh and feeds into the district heating system.

In addition, appliances which contain a lot of glass, such as television sets, produce a negative energy yield during incineration.

The energy yield from ethanol or biodiesel depends on the feedstock used.

However, a number of constraints are associated with wind energy, sucha as low energy yield.

Heart, passion, motivation and energy yield to software.

This is partially offset by higher energy yields of up to around 30%, for near-shore wind farms.

However, at higher latitudes, winter energy yield will be significantly reduced for non-south orientation.

Annual energy yield computation based on a Weibull distribution of wind speeds.

They produce the highest food energy yield of any cultivated crop, about eight to 10 times as much as corn.

Finally, it needs to be determined how to support the Improvement in the energy yield of coal-fired plants beyond 50% as soon as possible.

Many other states pay for energy efficiency programs at much higher levels.
