CleanTechnica

In recent posts on Planetsave and EcoWorldy about moratoria on soya and cattle products related to Amazon destruction, it was mentioned that McDonald’s is helping to save the Amazon. With the company also delving into green building, progressive energy saving software, and charging stations for electric vehicles, is McDonald’s a green company?

Herbs and spices like thyme, rosemary and mint, usually used to flavor food, can also offer a green alternative to synthetic pesticides.

Research has shown that oils derived from the herbs interfere with insect nervous systems, causing them to spasm haphazardly until they die. Best of all, these all-natural pesticides are inexpensive to produce.

Necessity is the mother of invention, and real needs will grow with climate change.

The most fundamental of these is the need for fresh water.

Despite predicted long-term water stress across a wide swathe of agricultural states like California,  we will have to find ways to grow the food we need. All kinds of novel adaptations must be made, from recycling water to learning to grow food in salt water and to reusing water that we do have.

Pond scum just got an upgrade.

SunEco Energy is working with J.B. Hunt Transport Services, a leading transportation company, to run trucks on biodiesel mixed with algae oil.

SunEco says a blend of 20 percent and 50 percent algae oil with petroleum biodiesel has cut particulate emissions by 82 percent. Read the rest of this entry »

You’ve seen the headlines:

Cows Operate Power Company as Side Business
Onion Farmer takes $2.5 Million to Bank For Electricity Production
More Carbon Sequestration Needed: Farmers Paid to Not Plant

Every day there’s more news of the alternative energy that farms can make. From cow poop. From crop residues. From onion skins. From chicken feathers. From wind royalties. From solar power.

But you read cleantechnica.

Of course farmers will benefit from the climate bill. HR2434 is designed to make it cheaper to switch to low carbon energy than to keep using fossil fuels that destroy our future.

Farmers; however, are stuck with Fox News and Rush and the Heritage Foundation and CATO. They are told

Your energy cost will soar under socialist Al Gore climate bill!

So they worry. What Fox News and Rush won’t let them know is that…

Sometimes, when you ask a question, you get a good answer.

A recent post on a push to increase the U.S. gasoline blend rate ended with this thought-provoker: At this rate, will cellulosic ethanol, from non-food plant materials, ever get off the ground?

Yes, replied Sam Salyer, a representative for a Massachusetts-based biofuel company called Qteros. Read the rest of this entry »

You’d think this would be a “Buy American” type of issue. Growth Energy, an ethanol industry trade group, wants to raise the content in gasoline from 10 percent to 15 percent in the United States.

The ethanol industry, of course, is firmly behind the proposal, made to the U.S. Environmental Protection Agency. Ethanol plant operators say a boost would bring jobs and investment on U.S. soil. Read the rest of this entry »

Those yummy California lemons, avocados, oranges, pistachios or cherries on your table right now could have been very sustainably grown using solar panels.

That’s because a giant California grower has just installed 1 MW of solar power to water their 7,000 acre farm. The 6,400 solar panels power pumps to bring water up from deep wells for irrigation.

(Normally these irrigation pumps are run by fossil fuels - one of the reasons that our food is so unsustainable.)

Just in time, too.
As climate change brings an increase in drought areas and rising sea levels we have to find a solution to soil salinity if our civilization is to survive.

Previous civilizations dependant on irrigation of dry soil have failed. The gradually increased salinity in irrigated dry soil has ended civilizations even though they solved the engineering and logistic problems of designing, building, and maintaining irrigation systems, but neglected the long-term effects of salinization.

We’ll have no choice but to learn to farm in salty water, as the next few centuries’ climate change dries up growing areas from California, Florida and the Middle East, to Africa and China and Australia - - and as seawater increasingly infiltrates crops on low-slung island nations.

So the research findings of a group of scientists from the University of Adelaide in Australia and Department of Plant Sciences at the University of Cambridge, UK. attempting to learn to grow crops in saltwater is very good news.

The team has succeeded in keeping salt out of the leaves of the first plant species tested:

A new way to treat wood has trees back in the limelight: a hardwood’s reliability that even a rain forest mahogany tree can love.

The above picture is of the world’s first heavy traffic road bridge made from Accoya® wood. The bridge, located in Sneek in the Netherlands, is “the first wooden bridge in the world that can support the heaviest load class of 60 tons”.  At this week’s Wall Street Green Trading Summit, a panel on forestation introduced a new way of thinking about how to deal with destruction of the rain forest.

>> More from the recent Wall Street Green Trading Summit:   Opening, Carbon Markets, Weird Investments and Solar Panels for All.

I think we can all agree that planting trees is a good way to go environmentally green (they capture carbon like crazy), but lets take a look at that other green for a moment: the green of cash.  Forestation can turn a profit quickly, given that it is one of the few industries in the United States that we know for sure will be cross marketable as a carbon offset industry.  Read the rest of this entry »
