Is it reliable or intermittent?

Solar and wind power can deliver that already, but not necessarily when and where needed. We need storage breakthroughs for these intermittent clean energy sources.

Windpower has a high EROEl, but is intermittent.

They remained in existence for intermittent, generally short, periods.

It's pretty much like the moon. It has intermittent eclipses.

An interconnected energy system would make particular sense for the UK and Germany, which could use the one hour time difference between them to smooth out the peaks and troughs in demand. Renewable energy production is by nature intermittent, and the sheer number of fluctuating power sources in Germany is already pushing its existing grid to the limit.

And my parents were very patient, but I had been doing intermittent sojourns to India on a mystical quest.

Between 0500 and 0600 hours an Israeli gunboat off Mansuri fired several intermittent bursts of medium weapons fire in all directions.

Between 0500 and 0645 hours an Israeli gunboat off Mansuri fired several intermittent bursts of medium weapons fire in all directions.

Between 0300 and 0600 hours an Israeli gunboat off Mansuri fired several intermittent bursts of medium weapons fire in all directions.

The intermittent wars and potential risks have impacted the development process of Western Asia more than any other part of the world.

Intermittent clan clashes and real and perceived security threats forced the Office of the United Nations Security Coordinator to implement stringent security controls.

There were intermittent clashes between Palestinian demonstrators and Israeli forces, particularly at Hebron, and a number of attacks by Palestinians on Israeli targets.

Drought and intermittent clan conflicts have resulted in the displacement of an estimated 400,000 people in Somalia who continue to live in extremely difficult conditions.

49. The situation in Somalia has been affected by pockets of drought, floods and intermittent fighting, thus requiring a flexible approach to reach vulnerable children.

Intermittent fighting continues in Somalia, and the prevailing insecurity and violence continue to prevent the United Nations from implementing programmes in large areas of the country.

What you're doing is, when you stand up, potential energy to kinetic energy, potential energy to kinetic energy.

a In the context of Renewables 2004, renewable energy sources and technologies include solar energy, wind energy, hydropower, biomass energy including biofuels, and geothermal energy.

When combined with renewable energy sources, hydrogen energy provides the ultimate clean energy system.

It is exceedingly difficult to convince such an individual that for an astronomer in a developing country, e mail, if available at all, is often intermittent and unreliable.

(b) Energy efficiency and financing cleaner energy systems

To acquire energy, you have to use energy.

Energy related projects focus on promotion of renewable energy, energy efficiency improvements (supply, distribution and end use), and energy sector management and market reform.
