New plastic holds promise of cheaper solar panels

Solar panels for use in long-term applications (generating energy for decades on roofs, say) are both stiff and heavy because they use glass to admit light but keep out water. But word comes now that a new plastic has the durability of glass but is lighter and flexible. The new plastic, from 3M, should last 20 to 25 years, the company says, according to a great report in MIT's Technology Review. The clear implication is that solar panels may soon be cheaper and require less energy to deliver.

Glass tile distributor to buy carbon offsets for all U.S. product shipments

Hakatai, a distributor of imported glass mosaic tile, will now use carbon-neutral shipping on FedEx Ground and Expedited orders within the United States. The company has partnered with GreenShipping.com to purchase carbon offsets through Bonneville Environmental Foundation, a non-profit organization.

I spoke with Amanda at Hakatai, and she told me that the company is using the partnership to buy carbon offsets for all product shipments in the United States -- and the company is absorbing the cost to do so. Hakatai will not increase prices or shipping cost to customers, she said.
