This ‘Monumental Shift’ in the US Buildings Sector May Surprise You
Conventional wisdom says that buildings are a sprawling, untamable black hole for energy. But a new analysis of federal data shows that the U.S. buildings sector has made enormous strides in efficiency over the last six years — potentially eliminating the need to build any new power plants to support growth in the sector through 2030.
When sustainable architecture guru Edward Mazria looked at the EIA’s latest Annual Energy Outlook, he noticed two surprising things: one, that 2030 projections for building energy consumption continue their steep decline; and two, that America plans to add over 60 billion square feet of new buildings by then. So even as a huge portfolio of new buildings is constructed in the next two decades, the energy needs in those buildings will be low enough to prevent the need for any new power plants to service them, concluded Mazria.
“There is no longer any need to build power plants to meet growth in the buildings sector,” said Mazria. “This is a monumental shift.”

With Carbon Dioxide Approaching a New High, Scientists Sound the Alarm
If uncertainty runs rampant in the global-warming debate, it is in part because scientific data is often too complex to be well understood by anyone but climate scientists.
This month, however, the world is likely to reach a scientific milestone that appears impressively scary even to those with only a cursory knowledge of climate science.
For the first time in human history, atmospheric carbon dioxide levels will surpass 400 parts per million, according Scripps Institution of Oceanography, which has been measuring carbon dioxide in the atmosphere at the Mauna Loa volcano in Hawaii since 1958.
“The 400-ppm threshold is a sobering milestone, and should serve as a wake-up call for all of us to support clean energy technology and reduce emissions of greenhouse gases, before it’s too late for our children and grandchildren.”
