While we are all aware that we should only be using BPA-free, reusable water bottles, at least now there are some new, earth-friendly alternatives to traditional plastic bottles. 

Green Planet Bottling has introduced a 100-percent plant-based water bottle that is carbon neutral and toxin-free, compared to bottles contained both petroleum and BPA.  Green Planet water is vapor distilled for taste and purity, and the bottles are fully recyclable and compostable in 80 days.

Bottles returned to Green Planet are ground into flakes and then hydrolyzed to make new bottles.  Consumers can find Green Plant water in 16.9-ounce bottles at schools, select restaurants, corporate settings, hotels, and convenience stores. Twelve-ounce bottles are due out later this spring

During the 2010 Solar Power Finance & Investment Summit in San Diego, a large crowd learned that Chinese companies have cash and interest in the US solar energy market, yet partnerships require patience and low risk.

To explore the opportunities, R. Thomas Hoffmann, Partner with Ballard Spahr, led a panel with three experts on Chinese solar investing. They were:

• Jimmy Chuang, is with GCL Solar, the largest polysilicon producer in Asia and the largest solar developer in China.  GCL has access to $4.5 billion.

• K. Scott Son, Vice President of Project Finance at Suntech, the largest producer of silicon PV in the world (nearly $2 billion in revenue in 2008).

• Sha Wang, Principal at Cybernaut Investment, a family company with US and Chinese roots and a $500 million solar investment fund.

William F. Stewart is the author of Climate of Uncertainty: A Balanced Look at Global Warming and Renewable Energy, from Ocean Publishing. He is co-chair of the climate change and energy practice at Cozen O’Connor.

CleanTechies had four questions about his new book.

CleanTechies:  You promise a balanced look in your title, and you give the global warming nay-sayers a chapter.  Why do you feel it’s important to take this approach?

William F. Stewart:  I know it is a cliché, but skepticism really is the lifeblood of science. Historically, it is through the intense questioning of conventional wisdom that advancement has been possible. Although there are certainly a lot of cynics and charlatans masquerading as skeptics, good faith skepticism itself must be embraced if we are to achieve new discoveries. (more…)

Scotland has approved ten marine energy projects that leaders predict could provide electricity for one-third of the nation’s homes by 2020 and make Scotland the world leader in wave energy.

The government awarded leases to companies to construct six wave energy projects and four tidal project off the Scottish coast in what experts say would be the first developments of their kind on a large commercial scale.

Construction would cost £4 billion ($6.1 billion) and require another £1 billion ($1.53 billion) in government funding to upgrade the national electric grid. But First Minister Alex Salmond said tapping into the resources of Pentland Firth, a strait north of Scotland that is known for its strong tides, can make the country the “powerhouse of Europe.” (more…)

The Department of Energy, under its Smart Grid Investment Matching Grant Program, provides reimbursement of 20 percent of qualifying smart grid investments.

Qualifying costs include, but are not limited to, certain manufacturing related costs, software that enables computers or other devices to engage in smart grid functions, and metering devices, sensors, and control devices that are capable of engaging in smart grid functions.

Recently, questions have been raised as to whether the DOE grant under this program is subject to federal income tax.

The IRS, in Revenue Procedure 2010-20, concluded that the DOE grant is not subject to federal income tax. (more…)

California recently approved the decision of a state-wide solar heating program consisting of almost $360 million financial incentives and market development funding by 2018. This initiative will soon be followed by rest of the country that lagged behind the world in installing solar thermal systems.

Global statistics show that the solar thermal industry is taking large steps in fulfilling heating and cooling demand in the world. Most of the countries around the world have adopted incentive programs for both solar water heating and space heating. Whereas in some countries, solar thermal systems have been widely utilized for so many years even without incentives.

The most important decision criteria for a household to install a solar thermal system is basically the payback times of their investment. The main driving factors of the investment payback time are the total cost of the systems and the cost of alternatives heating systems. (more…)

A new 42-floor London skyscraper will be the world’s first building to incorporate wind turbines in the design, an innovation developers say will generate 8 percent of the building’s electricity needs.

The Strata Tower, a 408-unit apartment building scheduled to open in July, will be topped with three 19-kilowatt turbines — each with five 29.5-foot blades designed to suck wind from various angles and accelerate it through tubes, generating as much as 50 megawatt-hours of electricity annually.

It will also generate about £16,000 to £17,000 annually through the nation’s new feed-in tariff, the developers say. (more…)

The harnessing of solar energy is expanding on every front as concerns about climate change and energy security escalate, as government incentives for harnessing solar energy expand, and as these costs decline while those of fossil fuels rise. One solar technology that is really beginning to take off is the use of solar thermal collectors to convert sunlight into heat that can be used to warm both water and space.

China, for example, is now home to 27 million rooftop solar water heaters. With nearly 4,000 Chinese companies manufacturing these devices, this relatively simple low-cost technology has leapfrogged into villages that do not yet have electricity. For as little as $200, villagers can have a rooftop solar collector installed and take their first hot shower.

This technology is sweeping China like wildfire, already approaching market saturation in some communities. Beijing plans to boost the current 114 million square meters of rooftop solar collectors for heating water to 300 million by 2020. (more…)

Bubble, Bubble, Methane is Trouble: A vast storehouse of methane under the Arctic Ocean has perforated and is starting to leak, researchers disclosed. While scientists have long been preoccupied with methane release from permafrost on mainland Siberia, the underwater stores in the adjoining East Siberian Arctic Shelf are much larger, and the release of even a small fraction could lead to a dramatic increase in global warming. Methane is a greenhouse gas at least 25 times more powerful than CO2.

Now a Word from Our Other Gases: It was a promising week in the world of fuels. A Colorado startup revealed a solar concentrator that can vaporize biomass and make high-yield synthetic fuels. British scientists explored enzymes in the gut of a boat-eating bug that could break down straw or waste wood. Meanwhile, a California newbie called Transonic Combustion claims to have invented a fuel-injection system that could boost mileage of plain old gas by 50 percent. The company registered 64 miles to the gallon in recent test drives. (more…)

(Reuters) – British Columbia has given the green light to 19 private-sector clean energy projects that will generate enough power to supply nearly 218,000 homes in Canada’s Pacific Coast province.

The approvals, announced late on Thursday by BC Hydro, the government-owned electricity utility, mark the first phase in the provincial government’s long-delayed push to generate more green power.

Fourteen of the 19 proposals are 14 run-of-river hydroelectric projects, in which river water is diverted through turbines to produce power without the use of dams. The remainder are wind power projects. (more…)
