The How and Why of Green Building

Buildings account for almost a third of global greenhouse gas emissions and the U.N. Environment Programme projects that if we continue with business as usual in the building sector, these emissions will double by 2030. Fortunately, green building is on the rise around the world.

Before Paris, Cause for Optimism

If the international community were to fully understand the threat of climate change, and the likely cost of mitigation and adaptation, perhaps we would commit to continued tax breaks and incentives, and propel the renewable energy transition toward completion. In the long run, I am sure this would be less expensive than coping with the consequences of continued growth in greenhouse gas emissions through 2050.

Osmotic power — prospect of sustainable energy, or water liability?

Today, Statkraft, a company in Norway, opened the world’s first osmotic power plant—a model of a sustainable energy system which uses osmosis to harness the energy of fresh water’s natural movement toward salt water through a membrane. The idea for power generated through the movement of water, due to osmosis through a specially designed membrane,… read more
