The "month-by-month" chart shows a definite economic downturn starting full bore in the April/May time period. Usage is now falling and is well below 2010 levels and approaching 2009.
In Russia’s far east, temperatures can fall to 35 degrees below zero. Many islanders herd reindeer. In January, oil crews drilled the world’s longest and deepest extended-reach well, 7.7 miles down into the ground and 7.1 miles out under the ocean.
Nanotechnology promises to enable tiny, intricate circuits powering devices on any surface. But unless they’re harvesting energy from something like a heartbeat, the devices can only be as small as the smallest battery.
Despite improvements in the design of wind turbines that have increased their efficiency, wind farms are rather inefficient, Dabiri notes. Modern farms generally employ horizontal-axis wind turbines (HAWTs)-the standard propeller-like monoliths that
While all other major electronics components--things like transistors, displays, and other circuitry--have been made transparent, no one had taken the time and effort to create a transparent power source.
At $10,000 a piece, electric-car batteries are too expensive to throw out or recycle into scrap materials.
American Electric Power's recent decision to scrap plans to capture and sequester carbon dioxide at a West Virginia power station is just the latest in a string of cancellations of carbon capture and storage (CCS) projects.
The humble street light is joining the ranks of wind turbines and solar power plants in supplying renewable energy to the electricity grid.
The ocean is a big place. And if you're going to steal a bunch of electricity from it, you'll need a big generator.
Chinese startup develops new, low-cost ways to improve the properties of lithium-iron phosphate, a leading electrode material.
A new ultra-wideband antenna printed on paper or plastic can harvest ambient energy, enabling wireless sensors to tap into electromagnetic currents in the air around them.
Engineers at MIT are tinkering with all sorts of advanced solar power technology, like self-assembling solar cells, virus-structured cells and an artificial leaf system that mimics photosynthesis. Their latest project can be printed on a regular shee
Oil won't run the world forever, but it will for the next few decades--so how do we get from here to the next energy economy?
California is unique by not just calling for utilities to lay out their grand smart grid plans but also asking them to quantify and measure progress. As advanced as California is with its smart grid ambitions, the initial reported metrics show that t
In these highlights from the hourlong session, Gates argues that nuclear power is still safer than all other energy options, rich countries aren’t spending enough on R&D, and installing solar panels on your roof is not helping to reduce CO2 emissions
A startup says its compressed-air technology could do a better job of storing the power generated by wind turbines.
Metamaterials that convert lower-energy photons to usable wavelengths could offer solar cells an efficiency boost.
Wind power is one of the fastest-growing forms of power generation in the United States, with more capacity added onshore than coal and nuclear generation combined over the past four years.
In the last several years costs for solar power have dropped significantly, driven by advances in manufacturing technology, improvements in efficiency, and government support, among other things.
Trapping sulphur particles in graphene cages produces a cathode material that could finally make lithium batteries capable of powering electric cars
The well-publicized failures of cold fusion may have tainted the field’s reputation, but physicists have been successfully joining nuclei with hot fusion since 1932. Today, research in hot fusion could lead to a clean energy source
The US ambassador in Baghdad said on Saturday that the State Department has asked for a $6.2 billion budget for Iraq in 2012, underscoring that its oil and gas reserves were critical for the world's future energy needs.
A recent study by the Natural Resources Defense Council (NRDC) made headlines when it revealed that the biggest energy drain in your house likely isn't the fridge, air conditioner, or heater--it is, unbelievably, the TV set-top box.
Today in the Things We Thought We Understood But Really Don’t file, a Northwestern University researcher has upended what was previously thought to be a pretty good understanding of how static electricity works.
The wildfires burning in across the Southwest have threatened homes, economies, and communities, but today the Las Conchas fire in New Mexico is taking the threat to a new level.
Soon, when you sleep through your Monday morning alarm, it may be Uncle Sam’s fault. Federal officials are considering an experiment on the nation’s electrical grid that could interrupt the way your appliances tell time.
Regulators from Italy to Switzerland to Texas moved to stop pending nuclear-power projects, and the U.S. Nuclear Regulatory Commission (NRC) began to reevaluate the safety of all domestic plants.
The United States is seeing a natural gas boom thanks to discoveries of abundant shale gas, and at the same time a groundswell of opposition from critics who say the environmental risks from drilling are too great.
Typically, it’s explained as a product of electrons transferred in one direction between unlike substances, like glass and wool, or a balloon and a cotton T-shirt
A new energy source, one that we ourselves could produce, and the technology and economic force it would release would empower us to take control of our lives and the future. We’d no longer look to the system, but to ourselves...
