Enabling Wind Power Nationwide

Friday, May 22nd, 2015

UNITED STATES DEPARTMENT OF ENERGY
Today, wind energy provides nearly 5% of the nation’s total electricity generation. With 65 gigawatts (GW) deployed, utility-scale installations in 39 states, and wind power generation exceeding 12% in 11 of those states, wind is a demonstrated clean, affordable electricity resource for the nation. Research and industry experience indicate that wind can be deployed at higher levels while maintaining grid reliability.

Solar Paneled Roadways Vindicated

Sunday, May 17th, 2015

Last year I wrote a piece discussing the possible use of solar panels as road surfaces. In it I discussed a project by engineer Scott Brusaw intended to take our decaying roadways, contributors to climate change, and repurpose them to become part of the solution. Solar power generating roadways, he argued, could virtually eliminate dependence on carbon emitting fossil fuels for decades to come.

Lawrence, MA: Old Rails to Green Trails

With the help of EPA’s $200,000 Brownfields Area-wide planning grant, this video shows Lawrence Mayor Dan Rivera and Congresswoman Niki Tsongas explain the catalytic impact of EPA funding to jumpstart improvements and community outcomes for citizens in underserved communities, such as Lawrence, MA. By planning for, and envisioning, new walking paths to replace a blighted old railway that cuts through the City, residents will someday be able to link to adjacent recreational trails. This video shows the “before” of a key community project that will change the future face of Lawrence and make a real difference to its citizens.

Tapping Iowa’s Wind Resources to Reduce CO2 Emissions

Thursday, May 7th, 2015
Of particular interest is the corollation especially observable in the 2010 – 2012 years, between the CO2

IOWA WIND ENERGY ASSOCIATION
In a conservative scenario it is estimated that Iowa wind could easily contribute a reduction of 15 million metric tons of carbon dioxide annually to the region outside of Iowa, and in a more optimistic but still moderate scenario Iowa’s contribution could easily be over 36 million metric tons annually.

Philadelphia, PA: SEPTA Cycle-Transit Plan

Friday, May 1st, 2015
FIGURE 1: LICENSED DRIVERS AS A PERCENTAGE OF THEIR AGE-GROUP POPULATION

SOUTHEASTERN PENNSYLVANIA TRANSPORTATION AUTHORITY
SEPTA’s ridership is nearing quarter century highs. In Southeastern Pennsylvania and across the United States, rates of both private auto ownership and use are down. The region’s three fastest growing demographic groups – “Millennials” (20-34 years old) , “Baby Boomers” (60-75 years old), and an influx of newly-settled immigrants of all ages – are less likely to own a car (or even a driver’s license) and are more likely to use transit. These emerging local demographic groups tend to not only rely on transit for commuting to work but also for other discretionary trips and often travel with luggage, strollers and bicycles.

Scott Bricker, Director, America Walks

Scott Bricker has worked for over fifteen years to make communities healthy and sustainable through bicycling, walking and urban design. Scott is proud to serve as the Director of America Walks, the only national organization dedicated to improving all aspects of walking in America.

…providing safe and accommodating walking routes for people effectively ensures that everyone has equal access to services and employment, education, recreation, where people play and pray, et cetera. It’s a fundamental aspect of equal mobility access. There’s also a fair amount of research that shows that communities that are walkable, that have places that are close to each other, are economically vibrant.
