A hydrogen fuel cell-powered hybrid electric bus supplied by UTC Power for the Alameda-Contra Costa Transit District has set a performance record by operating for over 10,000 hours. The milestone is another step toward reducing the life cycle cost of hydrogen fuel cell-powered vehicles, which produce zero emissions and are more than 50% efficient in terms of converting energy to power.
The average annual cost of running a Mitsubishi i-MiEV electric vehicle amounts to around $233 a year, equivalent to paying some $0.82 a gallon for gasoline, according to New Zealand’s EECA. EECA undertook the study as part of introducing a consumer label that offers “independent, comparative information on the efficiency and running costs of vehicles,” which, in turn, is expected to help the government meet a long term goal of increasing renewable electricity generation from 74% currently to 90%.
Nissan’s world wide Leaf sales are now over 10,000 but questions continue to be asked about the technology. In a recently released video Nissan Corporate Vice-President Simon Sproule answers six questions about the Nissan Leaf battery.
Two aircraft manufacturers – Boeing and Embraer S.A. – have joined with the Inter-American Development Bank (IDB) have in announcing they will jointly fund a sustainability analysis of renewable jet biofuel made Brazilian sugar cane.
The algae biofuel company OriginOil has been pulling out all the stops to bring low cost algae biofuel to the market, and Operation Green Stick looks like their biggest move yet. Operation Green Stick is the code name for OriginOil’s network of sensors that automatically control for hundreds of variables in commercial-scale algae biofuel operations.
Bicycles (most efficient mode of transportation known to mad) + bamboo (super fast-growing, environmentally friendly plant) = awesome bikes.
Some Indian companies are taking the lead in providing access to sustainable, low-cost energy that also seems to be linked to poverty reduction. Two of those companies, Abellon Clean Energy and SELCO, have seized the entrepreneurial reins in providing viable models hat can combat poverty
One knock against biodiesel has been the relatively large amount of fossil fuel required to produce it. That’s aside from the contentious issue of using arable land to grow crops for fuel, especially food crops. However, a new study of the energy lifecycle of soybean biodiesel reveals a significant improvement in efficiency over the past 20 years or so.
As CEO and co-founder of LST Energy Jim Trussler is a man on a mission: to promote growing and using hay, or rather concentrated hay pellets, for home heating across North America. Cheaper, cleaner, plentiful and renewable, the benefits of doing so look to be numerous and varied.
By all accounts, aviation is the most carbon-intensive form of transportation we use. But when you’ve got a million-pound aircraft, slipping the surly bonds of Earth isn’t an easy task . Engineers are constantly working to make aircraft more fuel efficient and more environmentally friendly, and several new technological innovations may finally make the future of flight a sustainable one.
