The Green Fight: Solar Panels vs. Trees

We’re supposed to save trees – not only because there are laws against cutting them, but it’s the right thing to do. So Sunnyvale couple Richard Treanor and Carolynn Bissett were doing a good deed by planting a bunch of redwood trees between 1997 and 99.

Their neighbor, Mark Vargas must also be environmentally conscious, as he installed solar panels on his roofs in 2001.  There’s only one small (actually large) problem: solar panels don’t work without exposure to the sun.

The redwood trees grew to be giants, some reaching 400 feet, and they cast a shadow on the solar panels.  The neighbors have been fighting for years and finally Vargas filed a lawsuit.  Last December a judge ordered the couple to remove the trees. They won’t appeal, as after spending $37,000 in legal bills and can’t afford the lawsuit anymore, so they will abide. 

The lawsuit, and decision was based on California’s Solar Shade Control Act, which requires homeowners to keep their trees or shrubs from shading more than 10 percent of a neighbor’s solar panels.

Now, here comes the controversial part:

Existing trees that cast shadows when the panels are installed are exempt, but new growth is subject to the law.

CA state Sen. Joe Simitian (D) of Palo Alto plans to change it.  The bill he introduced this week would protect trees that were planted before the installation of solar panels. Those planted next to already existing solar panels would still be subject to removal.

Here’s the NBC11 video.

Update:  2009-10 will be the perfect time to install solar, as supply is expected to exceed demand.

Former SAP Exec Emerges to Deploy Grid for Electric Cars

When Shai Agassi, President of the Product- Technology Group in SAP left the software giant this March, his parting line “to pursue interests in alternative energy and climate change” could very well be viewed as a fashionable update to the old cliche of “leaving to pursue other interests and to spend more time with family”.

But in hindsight it’s obvious Shai knew exactly what he wanted to do next, as laid out in his blog post on Alternative Transportation within days after his departure:

…electric vehicles will become a reality within a short time frame, and will be cheaper to operate within a short time…

The consumer needs to feel comfortable driving an electric car with a ubiquitous charging infrastructure…

The grid needs to support the new load from this moving electrical appliance…

He then goes on defining his future role:

If you followed the history of the introduction of electricity through the first appliance – the electric light bulb – you know that there were three main players in the story: Edison, Tesla and Westinghouse…

…Tesla invented most of the essentials for the common grid we know and love today. The guy who deployed it in mass scale though was Westinghouse, which is the role we need in this new electric revolution – the business guy who deploys with the highest efficiency and best business approach. If Tesla Motors are the modern day Tesla, my hope is to play the role of Westinghouse, or some small part of that role.

Half a year later Shai re-emerged, launching Project Better Place, a company funded to the tune of $200M, which intends to deploy the infrastructure needed to support electric vehicles.

Project Better Place wants to create the grid of recharge and battery exchange stations, and here comes the interesting part: they want to follow the mobile phone industry’s business model, offering subscribers to the grid subsidized cars that are “cheaper to buy and operate than today’s fuel-based cars”.

I’m sooo ready for a subsidized Tesla smile_regular

Update: Now that there’s a conversation going on about HaaS (Hardware as a Service), I’m going to declare the Shai-mobile CaaS: Car as a Service. smile_wink

Update: Watch Shai on CNBC, first live in the studio, then I believe remotely. Wonder why he put on a tie for the second round…perhaps Thomas knows(?)

Gotta love this quote:

This is not a science project. This in an integration project.
