Perhaps money really does grow on trees after all! Solar Trees are sprouting up in the parking lot of Dell Inc. (NASDAQ: DELL) corporate headquarters located in Round Rock, Texas.

It is estimated Dell’s “Solar Grove” project will provide 131,000 kW/h of clean solar power to the building, avoiding greenhouse gas emissions by about 145,000 pounds per year. But wait, there’s more. More than 500 individual solar panels will provide shade to some 50-plus parking spaces in the employee parking lot. Plus, the trees include two Coulomb ChargPoints for electric vehicles and plug-in hybrids.

Spanish Solar Company SOLARIG Building 8 PV Parks in Italy

SOLARIG, a company based in Spain that incorporated about four years ago, just began construction of eight photovoltaic parks in Italy this month. The parks will provide 8 MW of energy in total. Over the next few months, it plans to construct photovoltaic projects producing 30 MW throughout different regions of Italy.

But this is just the beginning. SOLARIG has a more global vision.

Solar panels on your roof? New law makes leasing possible

Parking garages typically serve one obvious function.

But drive to the top of the parking garage on First and Sierra Streets in downtown Reno, and you’ll realize that this is one facility that also can take the heat.

Solar panels have turned the garage from a one-trick pony to a building that harnesses renewable energy. And thanks to a new Nevada law, proponents of green energy are predicting that similar projects will become more common across the Silver State.

Renewable Funding, a company that makes it easier for homeowners to finance solar or other renewable funding projects with friendly terms, has raised $12.2 million in a first round of funding.

The Oakland, Calif., based company’s model is noteworthy because it lets you attach your financing to your property tax bill.

So if you sell your house after investing in an expensive solar paneled roof, the financing stays on your home’s property tax bill, even if you sell the house.
