German energy policy now depends once more on the future deployment of renewable energy sources.

Besides, it is more efficient to reward energy conservation rather than to simply penalize energy use.

We need to use energy far more wisely while shifting from fossil fuels to low carbon energy sources.

It also requires more energy efficiency, which means a reduction of waste in both energy production and consumption.

An energy plus house (also called Plus Energy House, Efficiency Plus House) produces more energy from renewable energy sources, over the course of a year, than it imports from external sources.

The goal is breathtaking more than 80 of Denmark s energy supply comes from fossil fuels, which are dramatically cheaper and more reliable than any green energy source.

Low carbon growth will be more energy secure, cleaner, quieter, safer and more bio diverse.

We want to get people to be more energy efficient.

Shifts to more energy efficient means of transportation ease congestion.

The first is energy conservation through more fuel efficient vehicles.

Hydrocarbon energy depletion is set to complicate matters even more.

Alternative energy sources such as solar and wind create significantly more expensive fuel and electricity than traditional energy sources.

But only if research is doubled to create new energy efficient technologies will we eventually consume less energy overall and more energy in an environmentally friendly way.

(b) More sustainable energy production. In order to escape from this unsustainable situation, farmers in Kenya are making significant efforts to use available sources of energy in a more sustainable way.

The projected rapid growth of nuclear energy will generate yet more challenges.

In other words, the body expends more energy than it takes in.

Some such mechanism will be essential in the coming decades as more and more countries introduce nuclear energy.

So my premise here is that nuclear energy puts out more carbon dioxide, puts out more air pollutants, enhances mortality more and takes longer to put up than real renewable energy systems, namely wind, solar, geothermal power, hydro tidal wave power.

Brazil s firms are far more efficient than America s subsidized industry, which puts more energy into getting subsidies out of Congress than in improving efficiency. Some studies suggest that it requires more energy to produce America s ethanol than is contained in it.

Coal is a cheaper and more easily used energy source than the alternatives.

Food and energy prices are more likely to be affected by monetary policy.

More efficient technologies normally take many years to spread through the energy sector.

The more energy efficient one is, the lower one s vulnerability to price volatility.

We will need improved energy efficiency, through green buildings and more efficient appliances.

They also work with the Institute for Energy Alternatives (IDEA) on energy saving ideas, and more sustainable forms of transportation to and from work.

Using more energy inevitably means emitting more CO2 at a time when climate change has become a critical global issue.

The problem is that green energy mostly is still much more expensive, less effective, and more intermittent than the alternatives.

In the photoemission process, if an electron within some material absorbs the energy of one photon and acquires more energy than the work function (the electron binding energy) of the material, it is ejected.

The trend by which consuming countries grow steadily more reliant on energy from a small number of producing countries threatens to exacerbate energy security worries.

We need many, many times more non carbon based energy than is currently produced.

Philip Verleger, a respected energy analyst, argues that, by 2023, the 50th anniversary of Nixon s Project Independence, the US will be energy independent in the sense that it will export more energy than it imports.

But when you change those behaviors, your brain gets more blood, you think more clearly, you have more energy, your heart gets more blood in ways I ve shown you.

I deal with the heat by using more energy, which leads to burning more fossil fuel, putting more greenhouse gases into the atmosphere and heating up the planet more.

The EU must become more active, more determined and united in securing its energy interests and those of its member states.

Any particles more massive than this energy limit aren't produced, and remain invisible to us.

Smelting copper ore, for example, is more than twice as energy intensive as recycling copper.

Moreover, economists contend that energy consumption per capita is declining, owing to more efficient use.

We need to use energy far more wisely while shifting from fossil fuels to low carbon energy sources. Such decisive improvements are certainly possible and economically realistic.

More energy is coming in than going out, until Earth warms up enough to again radiate to space as much energy as it absorbs from the Sun.

Azerbaijan shows some signs of the so called Dutch disease because of the fast growing energy sector, which causes inflation and makes non energy exports more expensive.

(a) Canada's wind energy resources are among the best in the world and it has installed more than 500 megawatts of wind energy capacity across the country.

Putin s efforts to transform Russia into a major energy power and use energy as a tool of Russian foreign policy make the region all the more strategically significant.

What is required, first and foremost, are market based incentives to induce Americans to use less energy and to produce more energy in ways that emit less carbon.

When considered in this wider European context, there was more symmetry in the Russia Ukraine energy relationship than the simple numbers on energy dependence implied at first glance.

Even among more near term projects, some for example, retrofitting buildings with more energy efficient features could become viable with action from policymakers.
