What It's Like Living off the Grid

Living off the grid means many things these days. Some say they're "off the grid" if they go camping and leave their mobile phone at home for a weekend.Others think being off the grid is living like hermits and runaways, stuck somewhere in between a bush and a hard place. Like the Canadian government we think that off-grid means being disconnected from electricity. Electricity, after all, is the mother of all grids.

EIA trims US gas production outlook

The US Energy Information Administration slightly trimmed its estimate for domestic natural gas production growth in 2012, but still expects output this year to be up 3.8 per cent from 2011's record levels.

 

In its August short-term energy outlook, the EIA said it expected marketed natural gas production in 2012 to rise by 2.5 billion cubic feet per day (bcfd) to a record 68.72 bcfd. That forecast was down slightly from its July outlook that had output this year at 68.98 bcf daily.

The Secret to Solar Power

The Secret to Solar Power | Développement durable et efficacité énergétique | Scoop.it
The future of solar belongs to whoever can convince consumers that it’s not just for tree-huggers and rich people.

 

"Silicon Valley has done a great job of talking about its disruptive potential, but there is something truly disruptive about solar: a fully distributed model of energy generation. We currently rely on the centralized hub-and-spoke delivery systems of the utilities, many of which are outdated and suffer tremendous losses as electricity travels from power plants, along transmission and delivery lines and into our businesses and homes. There is a massive infrastructure of regulation and enforcement in the energy market to underwrite the utilities; it’s one of the most highly regulated and noncompetitive markets in the country. Imagine a world in which homeowners and business owners are miniature power plants, with the full ability to sell power back to the grid at retail prices — power, literal and figurative, would be wrested from the hands of monopolistic, polluting utilities and their ancillary industries: mining, fracking and the like."

 

AN : The article is USA centric but the concpet of solar power to the grid is universal. First that...then the smart grid...

When we were young, our parents warned us not to sit too close to the TV. "Bad for your eyes," they said. No one knew that televisions were zapping us with radiation, the result of a little design flaw in the color sets sold in the sixties. But those were the days of lead paint, of chemistry sets with mercury droplets, of toy stores that sold radioactive rocks. What child didn't want to mutate radioactively into a superhero?

 

In the past five decades, popular attitudes towards these hazards have changed dramatically, thanks in part to the way television and other media have taught us to appreciate our planet's natural beauty and beware the dangers that industrial processes pose to the Earth and its inhabitants. The media have covered a host of ecological topics, from environmental science to the ways consumers can live greener lives. But they have failed to explain their own contribution to environmental problems.

 

A lot of people who work in the media wouldn't consider their jobs as harmful to the environment. But media and communications technologies are rapidly becoming some of the biggest energy consumers in the world. Household electronics were responsible for about 15 percent of global residential electricity consumption in 2009. In many homes, this is more than the power needs of traditional large appliances.

Transition énergétique : Quels liens entre croissance et énergie ?

Transition énergétique : Quels liens entre croissance et énergie ? | Développement durable et efficacité énergétique | Scoop.it

Le débat sur la transition énergétique s'annonce dans contexte économique très dégradé depuis 2008 et qui ne semble pas devoir s'améliorer dans les prochains mois. Dans ces conditions, la question du lien entre énergie et croissance revient en filigrane dans la plupart des thèmes abordés : nucléaire, gaz de schiste ou énergies renouvelables sont invariablement présentés par ceux qui les défendent comme des atouts pour l'économie française. Sans entrer dans ces polémiques, il est indispensable de se demander dans quelles conditions la politique énergétique pourrait permettre de préserver la croissance, ou au moins prévenir de nouvelles crises.

Why we need a World Environment Organization

Why we need a World Environment Organization | Développement durable et efficacité énergétique | Scoop.it

With climate change manifesting itself in the melting of Arctic glaciers and the drowning of small Pacific islands, in widespread species extinction, forest loss, desertification, and impending water shortages, the scope of environmental problems has changed. Long-term alteration of the earth’s climate is moving us into terra incognita that’s difficult or impossible to reverse. Recently, Hurricane Katrina provided a dreadful example of how human alterations multiply natural impacts. And this is only one of many escalating global environmental crises.

Le 11 mars 2011 est une catastrophe, naturelle, nucléaire mais aussi morale. Elle a mis en lumière la fragilité de la démocratie japonaise face à la "conspiration du silence" – comme l’écrit encore Oe – des compagnies d’électricité, des administrations, du gouvernement et des médias. Dès lors cette catastrophe peut-elle être envisagée comme la deuxième défaite du Japon après celle de 1945 ? Quel modèle inventer pour sortir de celui de l’après-guerre et de la reconstruction ? Quel peut-être un nouveau projet de société fondé sur la décroissance ou les énergies renouvelables ?

Gayer & Viscusi: Energy efficiency regulations, the environment, and ...

Gayer & Viscusi: Energy efficiency regulations, the environment, and ... | Développement durable et efficacité énergétique | Scoop.it
Ted Gayer of the Brookings Institution and Kip Viscusi of Vanderbilt University have a new Mercatus working paper that is a careful and thoughtful critique of the rationale, the methodology, and the outcomes of federal energy efficiency regulations. Using standard Pigouvian externality theory, most environmental regulations are based on the “market failure” rationale that individual actions create unaccounted-for and uncompensated costs. Gayer and Viscusi begin their argument with the claim that such a rationale for regulation is indeed valid, to the extent that such costs exist. It also matters whether or not those costs are relevant at the margin — would imposing a tax for a cost or a subsidy for a benefit change the individual’s actions in ways that would account for the externality? If not, then it’s an irrelevant externality.

"There are no Paxmans to quibble over details and no climate gainsayers to make arcane or inaccurate objections. And that is the real lesson of Ten Billion. Without the clamorous voices of climate change deniers who constantly question the minutiae of scientists' research or cherry-pick data, Emmott has shown that it is possible to make a straightforward, telling demonstration of the dreadful problems we face. We need a lot more sober, pithy work like this."
