Electricity consumption from the manufacture of artificial intelligence (AI) chips has soared by more than 350 percent worldwide between 2023 and 2024, according to new research from Greenpeace East Asia. In East Asia, the global hub for AI semiconductor production, growing electricity demand from AI chipmaking has been met primarily …
A novel lighting device using carbon nanotubes that could give competition to conventional light bulbs and fluorescent bulbs has been developed by researchers at Ecole Polytechnique in Lausanne, France. The device uses a central wire covered with carbon nanotubes that gives out electrons when a voltage is applied. These electrons …
When light passes from air to water, it is refracted. This refraction is dependent upon the index of refraction of water, which is basically the ratio of the speed of light in air to its speed in water. Scientists have demonstrated a negative index of refraction in a material. The …
The world's first solar-powered funicular, a type of cable railway, has started operating between Italy's Livorno town and the Montenero sanctuary. Photovoltaic (PV) panels on buildings bordering the funicular's parking lot supply 90 per cent of the electricity drawn by funicular's year-round operation. The PV panels are connected to an …
Nissan Motors Corporation and Renault SA of France have decided to develop cars with fuel cells that run on hydrogen. The fuel cell vehicles will be available in the market by 2005. Fuel cell cars run on electricity produced by fuels such as hydrogen. As the exhaust emissions consist of …
revolutionary Electric Vehicle Alternative, or reva, the brainchild of Chetan Maini, managing director of Bangalore-based Maini group of companies, is not another smoke belching fossil fuel guzzler. The noiseless piece of machinery, first developed in 1996, is electrically driven. reva , India's first electric car, has been much delayed in …
the long-awaited us energy policy is finally out and its contents have come as no surprise. For people in the oil and gas industry, it is a dream come true. But for environmentalists, it is a disaster waiting to happen. The reliance on fossil fuels rather than renewable energy is …
At least 11,000 Costa Rican homes will soon have access to electricity, thanks to a solar energy project. Solarica, a Dutch company, is investing us $11.5 million to provide solar energy to people living along the country's rainforests. At a monthly cost of about us $10, a household will have …
Electricity generated in space using light from the sun can now be converted into microwaves and transmitted to the Earth using technology developed by National Space Development Agency of Japan and Kyoto University, Japan. It requires a satellite equipped with a huge solar panel developed by the two institutions. The …
Solarica, a privately owned Dutch company, is investing US $11.5 million to bring solar energy to 11,000 families whose houses are scattered alongside the dense foliage of Costa Rica's rainforests. At a monthly cost of about US $10, a family will have access to 50 watts of electricity per day …
By dislodging every attempt for progressive green legislation from very early on in his presidency, George Bush is proclaiming his disregard for the environment and open support for expanding energy supplies. He is making no attempt to balance the two. He is also proving to be a poor role model …
The long-standing record for electricity produced by solar cells made from cadmium telluride has been broken by researchers working at the US department of energy's National Renewable Energy Laboratory. Cadmium telluride is used in one of the most promising technologies, called the
it 's been more than seven years since the authorities decided to set up a solar power project in Mathania, Rajasthan. Nothing has come of it, yet. The bidding process for the project continues. Allocated funds and precious aid lies unused. It was supposed to be a unique demonstration project. …
Networking equipment has become an integral part of the US economy. Technological advances invariably lead to more equipment, demanding more power. US is waking up to the fact that inefficient office equipment coupled with ill-managed power distribution systems cause huge power losses. A mere 2.5 per cent saving in the …
california's public utility commission (puc) has increased electricity prices by 46 per cent. This hike is the largest increase in the state's history. The prices have been increased in a bid to avert frequent blackouts that are threatening the state's economy and also to save the state's electricity producers from …
Twenty-five windmills, each 1.1 metre in width, have been installed on a Tokyo building, situated on the banks of river Sumida. These windmills also have solar panels attached on them and are, therefore, capable of generating solar power as well. To date, this is the largest concentration of small windmills …
An analysis carried out by the Environmental Energy Technologies Division of the Lawrence Berkley national Laboratory, based in US, shows that in the US office equipment used by the commercial sector consumes more than 70 per cent of the total electrical energy consumed. Use of electricity in residences has been …
the French government's plan to introduce ecological tax reforms got a serious blow on December 28, 2000, when the country's constitutional court rejected a planned industrial energy tax. The ruling threatens the government's wider ecological tax reform programme. The constitutional council's ruling was part of its review of the 2001 …
if one finds air pollution on normal days choking, then January 2, 2001 must have been a nightmare. As the northern electricity grid broke down, seven states of north India plunged into darkness. With water supplies cut, telephone lines down and disrupted railway services, generators in all shapes and sizes, …
Zambian forests are being threatened due to the large-scale exploitation of their resources for fuelwood. Though Zambia is a major producer of electricity, only seven per cent of Zambian homes are electrified
