Environmental issues are at the front of everyone’s minds lately. Everything from green computers to fuel-efficient cars are in the news and making an impact on climate change.
How does heating those cold winter nights affect the environment?
We’ve done a lot of reading and found that gas heating is much more efficient and environmentally friendly than electric heating. Electric heating comes in at only a 33% efficiency, which means that 2/3s of the energy being produced by the electric company, usually via coal burning, when you turn on the heat is actually going up into the atmosphere, not your home. Gas heating, on the other hand, can be as much as 80% efficient, and in most countries is subject to strict government ratings for efficiency.
Browse through a gas heater store like GasHeatersOnline and you will see a great commitment to efficiency and the environment. For example, forced air heaters, which at one time were under intense scrutiny and had a resulting bad reputation, are now government-regulated. As a result, they are some of the most efficient systems around. For heating large areas with a lot of people – workshops, construction sites, etc. – forced air heaters are now one of the best and most efficient heating choices. Continue reading
Blackle.com creator Toby Heap is earning thousands of dollars per day with his purported energy saving “black Google”. Does it matter if his calculations are wrong?
Blackle, a search engine powered by Google, was launched following a blog post by environmentalist Mark Ontkush, who conducted research to show that monitors draw more power to display white than black. Because the highest trafficked site on the web, search giant Google, is an all-white design, Heap decided to create a black Google, which would save an estimated 750 Megawatt hours per year.
Since then, Heap has been criticised by the media for cashing in on “eco-guilt” (he makes money from AdSense ads displayed on his site) and techies who argue that black draws more power for modern LCD monitors, and has a negligible effect on older CRT monitors. Continue reading
Society has become tuned in to the effects of global warming in recent years, but green computers remain a relatively unknown concept in mainstream society. There may not be an Oscar-winning documentary or famous global summit to educate the public, but green computing is a massive emerging issue in our climate-conscious society.
A lot of fuss is made over the impact of airplanes and cars on carbon emissions, but a recent study found that electronic devices such as computers are responsible for 2% of all carbon emissions – the same as airlines.
This is a huge chunk of unnecessary waste going up into our atmosphere, and for all the flak given to the airline industry, the computer industry has emerged relatively unscathed. Thankfully, IT giants like Google, Microsoft and Intel have, in recent years, been proactive on the issue and vowed to make green computing a priority. Continue reading
New York City Mayor Michael Bloomberg is awaiting results from a commission studying ways to reduce traffic and carbon emissions in Manhattan. The results are likely to include a congestion charge for entering Manhattan, modeled after the congestion charge in London, England.
New York – the “City that Never Sleeps” – is also the “City that Swells”, growing from 1.6mil people in Manhattan alone to 2.8mil during working hours. This says nothing of tourists, who also flock to the borough and its many landmarks. Although New York is known for its public transportation system (72% of Manhattan residents use mass transit, compared with an average of 5% across the rest of the United States), that’s still not enough to quell the traffic.
Bloomberg’s congestion charging plan would put more money into public transportation, while also making a move to cut dangerous pollution levels within the city. Continue reading
