How Much Is the Internet's Electric Bill? [INFOGRAPHIC]

How Much Is the Internet's Electric Bill? [INFOGRAPHIC] | Développement durable et efficacité énergétique | Scoop.it
The data centers that keep the Internet running require an incredible amount of electricity every year ... and they waste most of it.


While surfing the web, you’re probably more concerned with the charge left on your laptop’s battery. But how much power does it require to keep the Internet itself running?

Powering worldwide data centers for major web companies like Google and Amazon is a huge undertaking. Between the servers and their cooling systems, 'data barns' consume 30 billion watts annually, about 1.5% of global electricity. And at the rate the Internet is growing and adding users, expect that to rise significantly in the next several years.


Are these centers being run efficiently? What toll does it take on the environment just to make sure your Facebook status (and a billion other Facebook users’) reaches the masses?

It's time to redesign our economic system

It's time to redesign our economic system | Développement durable et efficacité énergétique | Scoop.it

The vital connection between economics and a healthy ecosystem is still not understood by mainstream economists and financial theorists – what will it take?



Systems scientists know that Sandy and the historic drought that preceded it are symptoms of an economic system design failure; a system designed for a set of circumstances that applied in the past – a huge planet, small economy, abundant resources, unlimited waste sinks – but which are no longer relevant.

Zero-growth is the 'new normal'

Zero-growth is the 'new normal' | Développement durable et efficacité énergétique | Scoop.it

US economic growth will be less than 1% in the next fourty years according to a new analysis by famous American investor Jeremy Grantham. The contrarian investor sees resource scarcity and higher resource prices as well as demographic factors as the main reason why our global economies will continue to struggle for new economic growth.

 

As always the gloomy predictions of Mr Grantham's piece make a lot of sense but will be neglected by the "don't worry, be happy" myopic political and economic elites.

Canada Smart Grid Project Helps Keep Surplus Wind Power Local | Renew Grid

Canada Smart Grid Project Helps Keep Surplus Wind Power Local | Renew Grid | Développement durable et efficacité énergétique | Scoop.it

Is there such a thing as too much wind power? The small city of Summerside, located on Canada's Prince Edward Island, is home to approximately 15,000 people and 21 MW of wind energy. However, sometimes the city does not need all that power and is forced to sell the excess to neighboring regions. A novel pilot program using electric heating and smart grid solutions aims to keep the wind power - and its associated benefits - within the city.

 

In 2003, the city's municipal government worked on a strategic plan to make its community greener, and the city ultimately decided to build and own its own wind power project. Aptly named the Summerside Wind Farm, the 12 MW project was commissioned in 2009 and comprises four Vestas 390 3 MW wind turbines.

 

Under the city's general fund, the taxpayers own the wind farm and sell the power to the municipal utility, Summerside Electric, which services about 7,000 customers and is contracted to buy all of the project's energy. In addition, Summerside Electric purchases another 9 MW of wind power from West Cape Energy, a company located on Prince Edward Island, for local use. Combined, both sources give the utility 50% wind integration.

 

But there is a problem: Summerside Electric has a peak load of 23 MW, a minimum load of 11 MW and an average load of 18 MW. With a wind capacity of 21 MW, the utility often has to sell surplus wind power to entities outside the city’s borders.

 

So why build and purchase so much wind energy in Summerside? Greg Gaudet, director of municipal services for the City of Summerside, explains that it makes more sense for the utility and community to have a proactive, rather than reactive, approach to power needs.

 

“When we looked forward, we said we’re not going to have this excess forever. Our load and community are going to grow,” Gaudet tells Renew Grid. “We could’ve either built just enough for what we currently need - which, in my opinion, means we would have been starting out already behind - or we could build for the future and have a little excess now. That will lead to more opportunities.”

L'Allemagne à la pointe de la transition énergétique

L'Allemagne à la pointe de la transition énergétique | Développement durable et efficacité énergétique | Scoop.it

Une production d'électricité d'origine éolienne et solaire parmi les premières d'Europe, une sortie assumée du nucléaire, des avances technologiques (sur la méthanisation par exemple), l'Allemagne est probablement le pays d'Europe et du monde qui est le plus avancé dans la transition énergétique, dans la sortie d'un système énergétique centralisé et dépendant de ressources d'origines fossiles. Elle est aussi le pays qui est le plus avancé dans la mise en place des "smarts grids", cet internet de l'énergie qui multiplient les infrastructures décentralisées de production et de distribution d'énergie.

Politicians and oil companies might waste time debating whether or not we’ve reached peak oil. What they ignore is that we run out completely in under 40 years’ time, by which time a third of the planet’s biodiversity will be lost.

In the meantime, tantalum, that great mainstay of mobile telecoms, will last only a few years more and run out just in time to celebrate the planet breaking the 2oC barrier in 2060.
There’s so much more words could say, but this, a very relevant and informative environmensl visualization, says is so much better...

Economics of energy efficiency: Beyond ROI - Consulting-Specifying Engineer

Economics of energy efficiency: Beyond ROI - Consulting-Specifying Engineer | Développement durable et efficacité énergétique | Scoop.it
Engineers and building owners often focus on payback periods and return on investment as economic decision-making thresholds for energy efficiency investments.

Back in the day, HVAC systems were designed to be stout, longevity was the main focus, and concepts such as operating costs and efficiencies were virtually non-existent. The driving force was purely “How much will it cost and will it last?” Interest rates and return on investments were left to the bankers and stockbrokers.

As the industrial revolution proceeded to where things are today, the world of business began to analyze effective measures to maximize profit. From a construction perspective, there are trade-offs with respect to material and equipment that engage the concepts of first cost and longevity.

The election is over and the people have spoken. After months of highly-charged attacks, lively and lackluster debate performances, and never-ending punches and counterpunches, Barack Obama has prevailed as the winner of the 2012 election.

 

It won't be an easy job. Mr. Obama will need to enable the creation of millions of new jobs, embolden U.S energy, environmental, and national security, and lead our country into a robust economic future -- all while dealing with a sharply divided electorate.

 

Now that the election is over, what steps can the president and new Congress take to ensure our nation's ongoing clean-energy leadership?

 

Here are five actions for Mr. Obama that, if implemented, we believe would supercharge the U.S.'s clean-tech economy:

IEA Oil Forecast Unrealistically High; Misses Diminishing Returns

IEA Oil Forecast Unrealistically High; Misses Diminishing Returns | Développement durable et efficacité énergétique | Scoop.it

"The International Energy Agency (IEA) provides unrealistically high oil forecasts in its new 2012 World Energy Outlook (WEO). It claims, among other things, that the United States will become the world’s largest oil producer by around 2020, and North America will become a net oil exporter by 2030."

 

Excellent critical analysis by Gail Tverberg of the over-optimistic new World Energy Outlook of the IEA.
