"Our economic system fails to properly account for the natural resources on which human prosperity depends. But attempts to remedy the problem, for example through environmental taxation, fail to address an elephant lurking in the room: the monetary system. Energy-related money offers a means to improve the qualities of the monetary system, while also stimulating the low-carbon energy transition we urgently need."
This type of electricity tariff works by your energy supplier purchasing renewable energy that matches how much energy you use in the home, this can be just some of the energy you use or all of it. On your behalf, your energy supplier will be purchasing renewable forms of energy from sources such as hydroelectric power stations and wind farms. You can request information as to which sources have been included in the purchase made on your behalf and also what proportion of the supply you have received is renewable.
In a lot of cases the green tariff will state that the energy they are supplying to you is renewable but they will only be assigning you the compulsory amount of renewable energy that they are already required to supply you with. This will reduce the amount of renewable energy that they are providing to their other customers and will not increase the amount of renewable energy that is being circulated around the UK.
Taisei Corporation is using its Ecological Reproduction System (Tecorep) to gradually lower the Grand Prince Hotel Akasaka, and bemused passersby have already witnessed the 140m-high (about 460 feet) tower quietly shrink to 110m (about 360 feet). It’s a far more elegant method when compared with the much-unchanged tack of getting something big and heavy and smashing it into a building, or the presumably fun but incredibly messy process of blowing it up. Buildings are of course dismantled using cranes already, but only from the exterior and for towers under 100m — and they’re far from green. Having investigated new methods since 2008, Taisei is suggesting that for buildings over 100m we need to adopt a new approach.
It appears the wave of major companies hiring their first full-time sustainability executives crested long ago. ... If hiring a senior executive to champion and coordinate sustainability efforts full-time is a leading indicator of future efforts, there’s a case to be made that such efforts may have plateaued. ... Could it be that pretty much everyone who’s coming to this party has already arrived?
Diamond has conducted numerous detailed examinations of civilizations that have met their doom and concludes a few things, notably that there is no single cause common to them all. “Anyone who tells you that they’ve identified a uniform factor for societies’ collapsing is an idiot,” he states bluntly.
There are, however, five themes that persist through all his investigations. I won’t give away the punch-line, nor will I provide my opinion as to how near or far the U.S. in the 21st Century is from breakdown; I’ll let you judge that for yourself from the content of the talk.
OK, I’ll give you a hint. The first one is people’s destroying their environment, i.e., inadvertently destroying the resource base on which they depend. The second is climate change; over the period of the past few thousand years on which Diamond has focused, societies’ local climate has gotten colder, hotter, wetter, drier, etc. Think about those first two for a moment: Is there any sense in which we’ve wrenched ourselves into a corner here?
– Head of the Sustainable Cities unit at the Danish Architecture Centre Søren Smidt-Jensen reveals: "To me, a sustainable city is the existing city.The future city is the existing city. The whole idea of retrofitting is the most crucial challenge of all."
