The Most Polluting Industries In The World

pollutionScientists have been sounding the alarms about climate change for decades, but unfortunately we are still completely dependent on digging stuff up and burning it for our main sources of energy. The United States gets 39% of its energy from coal, which is ok from a national security standpoint until the acid rain makes our water undrinkable. Natural Gas pollutes 30% less than coal and the U.S. gets 27% of its energy from that source, but there are still significant pollution issues. And, of course, there is a threat of a meltdown, but mainly the radioactive waste is dangerous for 240,000 years.

People have been looking for alternative energy sources for decades, but progress in getting them installed means less than 15% of the energy produced in the United States comes from renewable or clean sources. Hydropower is the largest sector of green energy in the U.S., responsible for almost 7% of the power production. It is, however, not without its own issues- dams can endanger ecosystems, so hydroelectric power has to be done properly. Wind is an emerging energy sector at almost 4.5% of America’s power grid. Just one percent of power produced in the U.S. comes from solar or geothermal sources, though that number is always increasing with improvements in technology.

Transportation is one sector where small improvements in efficiency can have a huge impact. Increases in mandatory fuel efficiency have decreased air pollution since the 1970s. Continuing to increase efficiency will continue to improve the environment. Biofuels have also shown promise in decreasing pollution. Now many people are even driving hybrid electric and full electric cars. When powered with solar power they produce zero emissions, and even when they get their power from traditional sources they still pollute less than traditional internal combustion engines.

Carbon Footprint of the Digital Age – Infographic

Footprint-recycle

This infographic looks at the impact the digital age is having on the environment. Taking proactive steps to lower your carbon footprint means more that switching of lights and reducing the amount of times you drive your car. Every time you switch on your computer or digital device CO2 is released into the atmosphere and polluting the planet.

Strong Greener Concrete with CarbonCure

Concrete is everywhere in construction, so I like to note what’s happening to make concrete “greener.”  CarbonCure Technologies, Inc. licenses technology in North America to make, for example, carbon-absorbed concrete blocks and other precast products.  Basically, CO2 is injected during curing — making limestone — with the end result being a stronger, greener masonry and other precast products.

Firefly is a New VAWT Small Wind Turbine

South Carolina-based Firefly Power is one of 20 other social- or environmentally-inclined companies presenting at the i2i Awards program in conjunction with SXSW Eco in Austin through Friday, October 5, 2012.  The company makes lightweight small wind turbines out of carbon-fiber blades in the vertical axis form.  The residential unit is rated at 1.8 kW, weighs less than 60 pounds, cuts in at 10 mph winds, and is expected to sell for about $7,000, according to Firefly Power.

Not So Big Timber Frame Home in Oregon

This is an 800-square-foot home in the River Road area in north Eugene. It was designed by Nir Pearlson and built by Six Degrees Construction for owners Rob Handy and Julie Hulme, who were inspired by The Not So Big House and other books by Sarah Susanka, FAIA. It turns out the owners upsized their situation by deconstructing an existing 620-square foot house built several decades ago, according to The Register-Guard.

The Greenest Home in the World [Video]

I was noodling some recent journalist potshots about headlines for “the greenest …” when I landed on this video piece from the Nightly News. NBC’s Kiko Itasaki wonders if this home in Unst, one of the northern Shetland Islands of Scotland, is the greenest in the world. Everyone knows the question has no answer, but I think Michael and Dorothy Rea have accomplished something worth noticing that’s for sure.
