Green Vehicles for Public Services: Potential Watershed for Clean Fuel Economy

July 29, 2009 :: J.E. Robertson :: No Comment Yet

One day, recently, I saw a fire-engine, crawling its way through a stop light, sirens blaring, hulking its way to provide the noble service of putting out someone’s fire or performing some other rescue operation. It was pouring a dark grey exhaust from one side, looking shiny new and well cared for, but obviously lacking advanced exhaust filtering or clean-energy drive technologies.

High-speed Rail Program Integral to Energy Overhaul

July 21, 2009 :: J.E. Robertson :: No Comment Yet

Pres. Barack Obama has proposed a national high-speed rail program that would develop eight to ten regions for high-speed rail (currently, only the so-called northeast corridor, running from Washington, DC, to Boston, through Baltimore, Philadelphia and New York, has a regular high-speed service), as part of a phased-in long-term economic recovery plan. The rail project comes into play also as part of Obama’s plans for a comprehensive energy-sector overhaul, aimed at reducing carbon emissions.

Eco-friendly Stadium Opens in Taiwan

May 21, 2009 :: staff :: No Comment Yet

The new stadium built for the World Games 2009, located in Taiwan’s Kaohsiung City, is being hailed as a landmark example of environmentally friendly building design. The stadium is rimmed with a partial canope roof that trails off into the surrounding promenade and is clad in 8,844 solar-voltaic panels, to generate electricity. The solar complex [...]

Texas to Deliver Wind Power to Millions of Urban Homes

August 11, 2008 :: J.E. Robertson :: One Comment

The state of Texas has approved a major new project to build transmission lines for wind power, with funding in the amount of $4.93 billion. Already the national leader with 5,300 megawatts of installed wind-power generating capacity, Texas will, when the infrastructure development is completed in 2013, have more wind-energy capacity than Germany presently does.The project is a major step toward freeing the American economy from high-contaminant power generation.

Renewable Energy Consumption & Electricity Preliminary 2007 Statistics

July 16, 2008 :: jr3o :: No Comment Yet

EIA Report: Renewable energy consumption declined 1 percent between 2006 and 2007 to 6,830 trillion Btu, according to preliminary 2007 data. In contrast, both total energy and non-renewable energy increased 2 percent. There was wide variation in the consumption behavior of individual renewable energy sources. Hydro electricity dropped 14 percent in 2007 due to reduced precipitation in several regions of the country. On the plus side, biomass-based energy grew 7 percent and wind-generated electricity jumped 21 percent. Major increases in consumption of biomass to produce and use biofuels (ethanol and biodiesel) were almost entirely responsible for the increase in biomass during 2007.

EPA Chief Says US Congress Should Legislate to Limit Carbon Emissions

July 12, 2008 :: J.E. Robertson :: 3 Comments

The chairman of the US Environmental Protection Agency (EPA), Stephen Johnson, says the Clean Air Act is “ill-suited” to fighting the greenhouse effect, and that Congress should pass laws mandating the regulation of carbon emissions, with global warming in mind. The move may lead to a more comprehensive regulatory regime, but as the Guardian newspaper notes: “Last year’s Massachusetts v. EPA Supreme Court ruling had found that greenhouse gases can be regulated under the U.S. Clean Air Act. The decision pressured the EPA to reconsider its refusal to regulate carbon dioxide emissions from new cars and trucks.”

Wind Power Set to Become World’s Leading Energy Source

July 10, 2008 :: jr3o :: No Comment Yet

In 1991, a national wind resource inventory taken by the U.S. Department of Energy startled the world when it reported that the three most wind-rich states —North Dakota, Kansas, and Texas— had enough harnessable wind energy to satisfy national electricity needs. Now a new study by a team of engineers at Stanford reports that the wind energy potential is actually substantially greater than that estimated in 1991.

Wind Energy Demand Booming

July 10, 2008 :: admin :: No Comment Yet

When Austin Energy, the publicly owned utility in Austin, Texas, launched its GreenChoice program in 2000, customers opting for green electricity paid a premium. During the fall of 2005, climbing natural gas prices pulled conventional electricity costs above those of wind-generated electricity, the source of most green power. This crossing of the cost lines in Austin and several other communities is a milestone in the U.S. shift to a renewable energy economy.

Clean Fuel: Toyota to Add Solar Panels to Hybrid Vehicles

July 7, 2008 :: J.E. Robertson :: 3 Comments

The green technology transition is gaining momentum. Japanese auto manufacturer Toyota has announced it will add solar panels to some of its fleet of hybrid vehicles. The “high-end” third-generation Prius models will sport Kyocera-produced solar panels on the roof, aimed at assisting with powering the air-conditioning and other peripheral operations, freeing up battery energy to give the hybrid engines more non-combustion mileage.
