New Materials Promise to Dramatically Drop Photovoltaic Prices

new materials like those in the "solar shingle" will dramatically reduce renewable energy costsWhat si the single most significant barrier to widespread use of alternative energy?  Is it the right wing climate change skeptics?  No.  It’s economics.  If there is not money to be made at the same scale as in the fossil fuel industry, and if renewable, clean energy does not become cheaper than fossil fuels, alternative energy doesn’t stand a chance in the free market.

As technology moves often faster than society, politics, culture, etc., the economics of alternative energy look brighter and brighter.

Achieving Net Zero Building Status Requires Occupant Engagement

All zeros: Net zero building requires occupant engagementOn February 26th, about 100 people gathered in San Francisco to discuss the world’s greenest buildings and the future of green building.  They discussed strategies that spawned a revolution in net-zero building as well as the frontier of new techniques and innovations.

Net-Zero, for those not familiar, is a term used to describe the net energy consumption and energy footprint of a building.  Whether a one-story garage or a skyscraper, a net zero building theoretically produces as much or more energy than it consumes.  Additionally, a net zero building does not produce carbon emissions.  This is often achieved through a combination of highly efficient design, carbon sequestration and offsets.

The February 26th convening came to an interesting conclusion: the future of green building is in the occupants, not the construction.  This doesn’t put the entire responsibility on the occupants.  Rather, it integrates behavior into the energy saving strategy.

The Growth of Efficient Buildings

Building efficiency is a growing trend serving both economic and environmental concerns The area of building efficiency affords tremendous opportunities for both economic growth and reduced environmental impacts. Buildings are the single largest emitters of greenhouse gases. According to a UNEP study titled “Towards a Green Economy,” homes and businesses are responsible for 40 percent of the climate change causing carbon pollution. There is significant room for improvement in new construction and retrofits in homes, businesses, schools and other organization.

In addition to environmental benefits, there are powerful economic incentives driving efficiency. There are a wide range of new innovations from analytics to smarter sensor technologies that offer cost effective opportunities for improvement. Read More→

Meeting the Climate Challenge: Cities Plan for Worst and Hope for the Best

Cities are where the most progress can be made to adapt to climate change and create a sustainable futureAt the national and international level climate action is stalled under the unyielding weight of factionalism and meeting the diverse agenda of a global community. At the personal level the issues of climate change and building a sustainable future for our children seems overwhelming; whatever efforts we can lend to the cause feels too small and inadequate.

In many ways meeting the challenge of climate change and sustainable development is often most effective at the municipal level. Cities strike a balance between meeting the diverse needs of its inhabitants with the ability to adopt and adapt to the realities and challenges of global warming, development, infrastructure and energy.  Read More→

Don’t Just Clean Your House; Green Your House

An example of a "postmodern" Solaris green home. Any house can be made greener!In the wake of Hurricane Sandy’s devastating impact on the East Coast, there has been contentious debate regarding whether or not we can attribute climate change to such a powerful storm. In fact, Bloomberg Businessweek didn’t pull any punches when it pummeled readers with its brash cover story.

But regardless of your stance on the issue, we can all agree that climate affects how we experience the world whether we’re at play, work, or leisure.

Although Sandy is an extreme and unfortunate example, it does serve to remind us that we are all susceptible to climate. Even in the simplest, most unexpected ways, weather has an impact on our daily lives. Take, for example, your home energy costs. This summer was one of the hottest in history; June alone broke 170 U.S. heat records nationwide, records that were established in the traditionally hotter months of July and August. How did your home cooling efforts go during the summer? More importantly, how were your home cooling costs? As we move into winter, your pocket book may see some relief, but keeping the house warm during the cold months presents another set of problems altogether.
