DAVIS, Calif. — As more homeowners generate their own electricity from solar panels, they still need power from a utility after the sun goes down.

Now, automakers say they may have an answer, by storing that carbon-free energy in electric car batteries for later use.

Honda on Tuesday is introducing an experimental house in this environmentally conscious community to showcase technologies that allow the dwelling to generate more electricity than it consumes.

It is one example of the way solar companies and carmakers are converging on a common goal: to create the self-sufficient home, with a car’s battery as the linchpin.

With buildings and transportation accounting for 44 percent of the United States’ greenhouse gas emissions, car companies increasingly view all-electric and hydrogen fuel-cell cars as vehicles that will meet environmental mandates and lead to development of new energy services and products beyond the garage.

After a seemingly endless winter, the first hints of spring have teased us with a day or two of temperatures over 60 degrees. That fleeting glimpse of warmth sent many New Yorkers flying out of doors to enjoy the sunshine. For my part, I sipped my morning coffee at home last week and stared wistfully out the window at a neighbor’s balcony.

In our concrete jungle, there is a hefty dollar value attached to having your own garden oasis — even the smallest of shrubberies carries a price tag. And with so many residents suffering from a vitamin D deficiency these days, brokers are promoting listings that can claim specks of green, even if they’re barely large enough to hold a bonsai.

Yet there are some listings for which the warmer weather was made.

Downtown, the average price of a luxury condominium with a terrace is $8.3 million; that compares with just $6 million for those without terraces, according to Vanderbilt Appraisal. And developers are doing whatever they can to take advantage of that pricing edge.

Grow a beautiful garden with ecofriendly greywater

You’re probably irrigating your yard with drinking water, since the same water that comes out of your kitchen faucet also comes out of your hose bibs. But do your plants need drinking water? It turns out that most plants are perfectly happy with gently used water from showers, bathtubs, laundry and sinks — or greywater (also “graywater”). This works out well, because the average American household uses about half its water indoors and the other half outside for irrigation. Some households can cut their water bills almost in half by irrigating with greywater.

Now that large swaths of the country are facing historic drought conditions — and the possibility that these droughts are the new normal — it especially doesn’t make sense to send usable water down the drain. You can recapture that water and use it again. There are other benefits to greywater, too. It reduces a home’s carbon footprint, since moving and treating water consumes a tremendous amount of power. It protects the aquatic ecosystems from whence your water comes. It reduces loads on sewage systems (which lowers the carbon footprint) and puts water back into the local aquifer, which is better than dumping it into rivers, lakes and oceans. If you’re on a septic tank, it reduces loads on the system, prolonging your service intervals. And it helps grow a beautiful and bountiful garden.

Greywater systems don’t look like normal irrigation. For one thing, there’s stuff in it — small amounts of soap, hair, laundry lint etc. You can either process the water and try to filter everything out, or you can use larger pipes and emitters and send the water to your garden as is. The latter is the better option — ideally, a greywater system should be low tech and dependable, with a minimum of parts to break and filters to maintain.

Salad from a car park

Rooftop farms in Singapore are sprouting greens.

Since the start of the year, Bjorn Low and his team of five have been growing small test batches of organic vegetables that can be used in mixed leaf salads – giant red mustard, mizuna, bok choy – and herbs such as basil and mint.

Like most farmers, they deal with pests such as pigeons nibbling on the plants. Team member Robert Pearce, 37, says jokingly: “I squirt the birds with water whenever I see them doing that.”

But unlike most farmers, the team’s plots are on the roof of People’s Park Complex car park – the latest rooftop farm to sprout in Singapore. Surrounded by high-rise buildings, the vegetables and herbs are a part of an urban farm, about 2,787sq m, slated to open on the sixth floor of the car park this year.

Last year, urban farming consultancy Edible Gardens, which helps restaurants and institutions build gardens, was approached by the car park’s re-development manager, Goldhill Developments, to see what could be done with the under-utilised space.

Low, 33, who co-founded Edible Gardens with Pearce in late 2012, says: “We’ve always been looking for a space like this to set up a commercially viable rooftop urban farm. This is our dream.”

NTU students bring green thumb to gray concrete of Taipei rooftop

TAIPEI, Taiwan — Around 60 ping of lush green covers the rooftop of National Taiwan University’s Sociology Department building, with strawberries predominant among the many rows. The notion of growing your own food in the concrete jungles of the city has long been a fantasy of urban dwellers, many of whom have sworn to devote themselves to a healthier, organic way of living.

Whimsical fantasies, it seemed, as concrete rooftops were less than ideal for growing, as the material absorbs and radiates excess heat in a way unhelpful to gardening. But a group of college students are now proud veterans of the gardening struggle between urban farmer and the limited environment.

The garden sprung from the course “Innovation and Design of Socio-economic Organizations,” in which a group of eight students decided that they were fed up with the money-driven flow that escalated housing prices outrageously in Taiwan, especially in the Wenlin Yuan case. When the Wang family accused the government of confiscating its land unlawfully, the students thought: aside from providing shelter, what else can “home” represent to people?
