In many cases, they do not have access to abundant sources of energy and have sought efficiency as a matter of energy independence--in the case of (No. 2) Denmark as an urgent national priority since the oil shocks of the 1970s.
Before 1998, most physicists believed that the universe contained far too little matter and energy.
But the fact of the matter is energy efficiency is a perfect example of how this can be a win-win.
The mission also hopes to give scientists a bigger clue as to the role dark matter and energy play in the universe.
Einstein's theory holds that matter and energy distort space, and massive bodies such as planets and stars travel in this warped space.
"In a world in which physicists have only recently discovered that we cannot account for most of the matter and energy in the universe, " the study says, it would be "presumptuous" to cling to the idea.
CNN: What's the matter with antimatter? Scientists want to know
Thomas Nagel, a distinguished American philosopher, once remarked that to say now that consciousness is a physical state of the brain is to be in the position of an ancient Greek who proclaims that matter is energy: what he says is true, but there is no understanding of how it can be true, no framework into which to fit the discovery.
Einstein's formula reveals the energy in nuclear reactions that convert matter into pure energy--something physically impossible with chemical reactions.
Light particles passing through the void would be expected to lose a little more energy than those passing through space cluttered with matter - if dark energy is stretching the Universe apart at a faster and faster rate.
BBC: NEWS | Science/Nature | Great 'cosmic nothingness' found
The book is organized by subject matter: Energy, Parenthood, Work, Marriage, Play, Spirituality, Mindfulness, etc.
Meanwhile, in space, scientists are looking for the signatures of dark matter and dark energy.
Among other things, this telescope is also looking for evidence of dark matter and dark energy.
Meanwhiel, in space, scientists are looking for the signatures of dark matter and dark energy.
The other 96% consists of dark matter and dark energy, two mysterious substances about which very little is known.
WSJ: The Weekend Interview with Michio Kaku: Captain Michio and the World of Tomorrow
Ecosystems are intricate networks in which matter cycles and energy flows.
FORBES: Daniel Goleman on the Importance of Ecological Intelligence
The entire tax could be rebated at a flat rate to all Americans no matter how much energy they use, making such a shift moderately progressive.
The First Minister has raised the matter of devolving energy consents directly with the UK Government, on three separate occasions since the Welsh election in May.
It also confirms that the proportions of normal matter to dark matter to dark energy are exactly what is needed to make space flat, rather than curved.
In the aftermath of these collisions, physicists hope to find footprints that prove the existence of a handful of things their calculations say should exist, like black holes, dark matter and dark energy.
But no matter how much energy you put into building a sandcastle, it's unlikely to be as impressive as the structures produced by Stone Spray, a solar-powered, robotic 3D printer that can create entire buildings out of sand.
Since, as every schoolboy knows, when matter and antimatter meet, they annihilate each other in a burst of energy, the equal amounts of matter and antimatter should have annihilated each other long ago and the universe should now be filled with energy and little else, which is evidently not the case.
Most of the challenge, as we often see for solar cells, is just a matter of improving the energy conversion rate.
Energy Secretary Steven Chu is on a mission to proliferate the use of clean energy no matter the cost to American taxpayers.
This is not a small matter, given that Energy Secretary-nominee Dr. Ernest Moniz is being grilled this week on Capitol Hill over some of these very issues for which he will soon be responsible.
As a general matter, the Statement of Energy Effects should be prepared at the level of detail appropriate and practicable for reasoned decisionmaking on the matter involved, taking into consideration uncertainties, the significance and complexity of the decision, and the need to adequately inform the public.
WHITEHOUSE: Memoranda 01-27 (Guidance for Implementing E.O. 13211)
The Alpha Magnetic Spectrometer was designed to search for dark matter by collecting high energy radiation known as cosmic rays, and then sort through it looking for a certain class of particle believed to be created after two bits of dark matter collide in space and destroy each other.
FORBES: Experiment May Have Found Dark Matter, The Key To A Cosmic Mystery
In the last few years, many companies have begun adopting energy saving technologies as a matter of good business in a world with high and volatile energy prices.
FORBES: Moving Energy Efficiency Beyond The Business Case for Sustainability
Both theory and previous observations suggest there is more dark energy than dark matter, and more dark matter than normal matter.
