Some of the issues that need to be addressed, he says, are the lack of any tax on aviation fuel, fiscal incentives for alternative-fuel vehicles, and the need for a carbon tax to replace the government's ill-directed climate-change levy.
Mike Brown, an executive with UTC Power, a leading fuel-cell maker, said the fuel cells need to last at least four or five years for the technology to be competitive.

If this technology is adopted when wind prices are low or even potentially negative, it can supplant the need for fossil fuel-based heating.

The need for the fuel-saving orbit was the result of a technical problem early on in the mission (it was originally intended to arrive in 1999).
ECONOMIST: The current crop of Mars missions has got off to a bad start
The plasmatron probably wouldn't be able to power a fuel-cell vehicle by itself or eliminate the need for hydrogen-fueling stations but, say the engineers, it could be a bridge to hydrogen technology.
If we really want to significantly replace fossil fuel-based power with renewable energy, then we need to get the public to care more.
"What I think we really need to focus on are more fuel-efficient vehicles, better city planning for the number and types of vehicles on the road, and more public transportation options, " Curtis Lewis said.
Until the day when the world can supply its colossal energy needs with 100% renewable energy, we need to decarbonise existing fossil-fuel power production, and CCS is a vital part of the carbon abatement strategy.
As the Syrian refugee crisis begins its second winter, Lebanese host households are struggling to cope with the burden of increased expenditures, decreased living space, and an ever-increasing need for more food, fuel and basic living necessities.
Agricultural landscapes can accomplish this while improving food and fiber production and minimizing the need for artificial fertilizer and fossil-fuel-driven tilling and raising farmer incomes.
While there is no doubt that wind, solar and geothermal have ample energy to power the planet--the sunlight that hits Earth in a single hour contains enough energy to fuel the human population for a year--they will need years to mature before they reach anything approaching their potential.
We need to show them that if they manufacture fuel-efficient cars and trucks, people will buy them.
"We need a dramatic shift off carbon-based fuel: coal, oil and also gas, " Bill McKibbern, the founder of 350.org, wrote in an email to The Associated Press.
The light trucks coming to market like the next-generation Chevrolet Silverado pickup and Ford Transit cargo van feature loads of fuel-saving technologies, proving you can have the space and capability you need and still get decent gas mileage.
Cheap fuel and mass-produced cars led to a shortage of road space and the need for pollution controls.
Drivers in the U.S. need a powerful set of wheels that can travel 500 miles between fuel-ups.
Many of these resolutions are focused directly on fossil fuel companies like Exxon, coal-fired electric utilities and hydraulic fracturing operators whose practices need cleaning up.
FORBES: Fossil Fuel Divestment Is A Timely Issue For Investors
Hybrids need to be equipped with larger battery packs, smaller and more fuel-efficient engines and a "two-mode system" that uses a pair of electric motors that propel the car at lower speeds.
Furthermore, the company is involved in such a range of energy technologies (including dirty coal plants, nuclear generators, natural-gas turbines and wind) that it does not need carbon regulations in the way, say, a narrowly focused fuel-cell or solar-cell maker might.
Exelon's Rowe estimates that electricity prices will increase by at least 15 cents per kilowatt-hour, due to upward pressure on the need for new capacity, fuel prices and capital and labor costs.
The upper flashing lights are integrated into the roof panel, eliminating the need for a bolted-on light bar that causes aerodynamic drag -- reducing fuel economy -- and can lead to rust.
Just as plants need sunlight to pull off the trick, Air Fuel Synthesis, the firm profiled in the UK's Independent newspaper, need to use good old-fashioned electric energy to pull off theirs.
There will need to be stockpiles of fuel, generators, and alternative communication methods, since a worst-case scenario might include not only an eruption but also quakes and subsequent damage that could severely disrupt TV, Internet, radio, etc and hamper relief efforts in many ways.
FORBES: What Can Be Done To Mitigate The Effects Of The Looming Mt. Fuji Eruption?
Ultimately, celebrity-endorsed or not, the quality of the product and the underlying value proposition will need to fuel a sustained interest and excitement for the brand.

In addition to strengthening the ATF's enforcement power, we need to attack gun trafficking at its source by limiting the high-volume gun sales that fuel trafficking from licensed dealers.
In partnership with a local technical college, Stark State in Canton, and Lockheed Martin, TMI is developing a military application that promises to greatly reduce the need for a front-line unit to transport and secure large quantities of gasoline or diesel fuel.
