A particular focus in 2011 will be on energy efficiency.

The power company found that few people wanted to hear about energy efficiency.

There is also a very clear focus on energy efficiency.

It is quite right for us to be talking about energy efficiency.

"But in the end energy efficiency is good for industry, not bad."

It is built with a focus on energy efficiency and the environment.

Will you take any steps on the action plan for energy efficiency?

Yes, we need energy efficiency, but that is not enough.

The key to the deal, to be signed today, is energy efficiency.

It will lead efforts in an increased drive for energy efficiency.

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

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

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

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

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

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

However, high energy yield can be realized with existing cultivars.

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

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

Systems are generally designed in order to ensure the highest energy yield for a given investment.
