Terror Management Theory

It seems we are well aware of our mortality and the meaninglessness of life, but expend huge amounts of energy that things are otherwise.One of the key mechanisms are religious beliefs and the world views constructed by adherents.Maybe we should cut to the chase, and stop criticising individual religions and the actions of their adherents?But … Continue reading Terror Management Theory

Protecting Health from Climate Change

http://www.who.int/world-health-day/toolkit/report_web.pdf STATEMENT BY THE DIRECTOR-GENERAL OF THE WORLD HEALTH ORGANIZATION Last year marked a turning point in the debate on climate change. The scientific evidence continues to mount. The climate is changing, the effects are already being felt, and human activities are a principal cause. In selecting climate change as the theme for this year’s … Continue reading Protecting Health from Climate Change

Climate Change and Human Development

I think Alma-ata and primary health care are critical to resolve this. As well as mapping health needs and taking action, energy, food and transport also need to be mapped and appropriate actions taken. http://www.thelancet.com/journals/lancet/article/PIIS0140-6736(13)62046-2/fulltext?elsca1=ETOC-LANCET&elsca2=email&elsca3=E24A35F Page 1154, 5 October 2013 Copyright © 2013 Elsevier Ltd All rights reserved.

Net-Zero Energy Buildings Take Hold in U.S.

Buildings that produce as much energy on-site as they consume are becoming more common

A weak economy and rising energy prices have led to a buzz over building efficiency. Light bulb regulations, LEED and Energy Star ratings for homes and appliances, stricter construction codes, and government incentives are all parts of a national effort to cut energy waste in the building sector.

Nearly 40 percent of the nation's energy is consumed by homes and commercial buildings, which means that making them more efficient would not only save money but also drastically reduce carbon emissions. So a handful of builders are taking the idea one step further: Why construct a building that uses less energy when we can make one that uses no energy at all?

That's the philosophy behind "net-zero" buildings, and they have been springing up all over the country in recent years. By the purest definition, a net-zero building produces all the renewable energy it needs on site, drawing no more power from the grid than it gives back.

Considering that a shack in the woods is technically net zero, the concept isn't exactly new. But advances in technology over the past decade have made it easier to design sophisticated buildings that produce 100 percent of their own energy. At least 21 commercial buildings in the United States meet net-zero standards, according to a study released yesterday by the New Buildings Institute and the Zero Energy Commercial Building Consortium.

They run the gamut from offices to libraries to elementary schools. Researchers identified eight more unverified buildings that may also be net zero and an additional 39 that would classify if they installed more on-site renewable energy systems, plus dozens more under construction.
