LAS VEGAS (AP) — While autonomous driving is a major theme at the International CES gadget show, cars that use futuristic sources of energy are potentially much closer on the horizon.
Ford Motor Co. showed off a prototype solar hybrid car called the C-MAX Solar Energi, which has a gas engine along with rooftop solar panels that also power the engine. The car is designed to park under a 15-foot-tall carport made of a thin magnifying glass called a Fresnel lens that concentrates the sun’s rays onto the panel to efficiently generate electricity. The carport isn’t portable. So the car has to stop and recharge.
Seven hours of sunlight gives a full charge — the average amount of light in a typical American city, according to Michael Tinskey, Ford’s associate director of vehicle electrification and infrastructure.
The vehicle must park facing east-west and inch forward to make the most of the sun’s rays as it passes overhead. With the movement, it’ll get a full charge, enough to run 21 miles on electricity only. Without the movement, it’ll get only 3 miles of juice on a seven-hour charge, before the gas engine needs to kick in.
While the car is being tested on streets now, engineers have more to figure out. For example, the carport is set up to be flat, making it vulnerable to weather.
“We’ve got to figure out snow, we’ve got to figure out rain,” Tinskey said. “We know we’ve got more work to do.”
Also on display is Toyota’s hydrogen fuel cell vehicle, called FCV for now. It will go on sale next year in the U.S. With a battery that uses hydrogen stored in a 5-kilogram (11-pound) tank and oxygen that rushes in through the front grill, the electric engine vehicle can get 300 miles while only emitting water and water vapor.
The main issue for eco-friendly owners will be finding enough hydrogen refueling stations to drive a decent range. California has approved $200 million in funding to build 20 fueling stations by 2015 and 100 by 2024. Toyota says as little as 68 stations will support 10,000 vehicles in the state.
The car’s hydrogen power source is harvested in a chemical process involving natural gas. It is already being used in industrial processes like oil refining, and there are pipelines zig-zagging beneath major cities like Los Angeles, said Jared Farnsworth, senior engineer of powertrain system control for Toyota in North America.
With hydrogen prices expected to be about $6 to $10 per kilogram — equivalent to $30 to $50 to fill Toyota’s FCV — there won’t be much savings for owners used to getting hybrid vehicle mileage, especially because the car is expected to be priced from $50,000 to $100,000 when it goes on sale next year. But the Earth might thank them later.

Bike share programs have revolutionized transportation in some of the country’s largest cities, like Washington D.C., Minneapolis, Miami Beach and Boston.
For a daily or annual fee (usually around $7 or $75 respectively), users can check out a bike for about 30 minutes at a stand-alone kiosk, ride it around the city, and then check it in at any other kiosk in the system with no extra charge.
The idea has been popular overseas since 2007 and there are now massive programs in cities like Paris (16,000 bikes), London (8,000), and Hangzhou, China (65,000). a href=”http://www.huffingtonpost.com/2013/05/27/citi-bike-share-program-launches_n_3342202.html” target=”_blank”New York launched it’s own 10,000-bike version, Citi Bike, earlier this year/a.
Many other cities (like Portland, Seattle, Detroit, Chicago, and Los Angeles) have programs in the works.
The Electric Car
Electric cars are finally starting to gain some traction and become reasonably affordable. a href=”http://www.businessinsider.com/cnbc-and-cnn-tesla-model-s-review-2013-2″The Tesla Model S/a, a href=”http://www.huffingtonpost.com/2013/02/20/nyt-vs-tesla-feud-reaches-end-of-road_n_2720770.html”subject to some recent bickering/a, has a range of about 275 miles on a single charge and a starting price tag around $50,000.

But the main concern is the youth of the industry. At home charging stations are recommended for most electric vehicles, but there isn’t a a href=”http://www.huffingtonpost.com/2012/10/23/electric-car-charging-stations_n_2002448.html”widespread public system/a that can rival gas stations, making long distance trips more difficult.
LEED Building Standards
The U.S. Green Building Council’s a href=”http://new.usgbc.org/leed”Leadership in Energy and Environmental Design/a system (LEED, for short) has revolutionized eco-conscious building initiatives across the globe. Companies looking to pump up their environmental track record are a href=”http://www.nytimes.com/2012/03/08/business/global/international-interest-grows-in-green-building-certification.html”spending time and money/a to have their buildings certified green.
LEED projects a href=”http://new.usgbc.org/leed/applying-leed”are in progress in 135 different countries/a, and more than half of certified square footage is outside the U.S.
A USA Today report criticized the system as a href=”http://www.usatoday.com/story/news/nation/2012/10/24/green-building-leed-certification/1650517/”being too lenient for some buildings/a, which only need to get 40 points out of 100 to receive a certification.
Cheaper Alternative Energy
The cost for renewable energy a href=”http://www.mnn.com/earth-matters/energy/stories/renewable-energy-costs-falling”continues to fall/a and is starting to become much more economically competitive with fossil fuels. New reports from the a href=”http://www.irena.org/home/index.aspx?PriMenuID=12mnu=Pri”International Renewable Energy Agency/a show the cost of solar falling more than 60 percent in the past few years alone.
Increasing competition has helped push the price down, particularly with solar as U.S. and European manufacturers struggle to keep up with a href=”http://qz.com/41166/how-germanys-energy-transformation-has-turned-into-a-crisis/”the pricing of Chinese solar panels/a.
a href=”http://go.bloomberg.com/multimedia/wind-innovations-drive-down-costs-stock-prices/”Wind power has also gotten consistently cheaper./a
Reusable Bags/Plastic Bag Bans

Better Ways To Throw Stuff Away
The average American throws about a href=”http://www.huffingtonpost.com/2012/08/21/food-waste-americans-throw-away-food-study_n_1819340.html”40 percent of their food /a away every year, and nearly 100 cities have launched composting programs to try and keep it out of landfills.
Curbside composting has spread across the country from uber-green San Francisco, which started their program 15 years ago and now collects a href=”http://www.motherjones.com/environment/2012/09/why-doesnt-your-city-have-curbside-composting”more than 600 tons of compost daily/a.

Lightbulbs have changed quite a bit lately. Compact fluorescent lamps were introduced as highly efficient alternatives to traditional bulbs before 100, 75, 60 and 40-watt incandescent lightbulbs a href=”http://www2.epa.gov/cfl”are phased out of production by 2014./a
But now, the new lighting revolution is in LED. These high-tech bulbs a href=”http://www.huffingtonpost.com/2012/04/23/philips-twenty-20-year-led-lightbulb-prize-department-of-energy_n_1445780.html”last upwards of 20 years/a and use minimal energy.

Community Gardens / Local Food Movement
Community gardening isn’t really that new, but the local food movement is. The demand for a href=”http://seattletimes.com/html/pacificnw/2008817652_pacificplife15.html”plots in p-patches/a or local green spaces has skyrocketed in the past few years as people opt out of GMOs and out-of-season produce (a href=”http://grist.org/locavore/local-haterade-authors-say-locavores-do-more-harm-than-good”which some argue is actually more carbon friendly/a).

The U.S. Department of Agriculture estimated the local food industry to a href=”http://www.huffingtonpost.com/2011/11/14/locally-grown-food_n_1092146.html”be $4.8 billion in 2008 and upwards of $7 billion in 2011/a.
Death isn’t the best thing for the environment. Cremation sends more than a href=”http://www.huffingtonpost.com/2012/09/13/green-funerals-options_n_1880096.html”6.8 million tons of carbon emissions/a into the atmosphere every year, caskets take a long time to biodegrade and burial leads to methane emission (a href=”http://epa.gov/climatechange/ghgemissions/gases/ch4.html”the second most prevalent greenhouse gas/a).
But a href=”http://www.huffingtonpost.com/2008/04/22/green-funerals-how-to-mak_n_97940.html”environmentally-friendly burial options/a are becoming more prevalent. Wicker and cardboard coffins can replace traditional wood, and dry ice is used rather than formaldehyde.
a href=”http://www.greenburialcouncil.org/finding-a-provider/SearchProviderSearchForm?mainsearch=CasketsmainsearchField=OrgProductTypeaction_searchproviders=Search”And green burial services/a are popping up around the globe to curb post-mortem emissions.
