Clean Energy 2030: Google's plan to save the planet

By Jonathan M. Gitlin

The twin pressures of climate change and the reliance on imported oil from politically unstable regions of the globe both point to a need to transform the way that the US sources, generates, and uses power. To that end, the search engine giant Google (which is developing itself some impressive green credentials) has issued a plan, Clean Energy 2030, that lays out a possible future for the energy and transportation sectors that promises to cut CO2 emissions, reduce dependence on foreign fuel imports, and save the economy billions over the next 22 years.
he Google plan is nothing if not ambitious. To begin with, Google proposes a massive push toward energy efficiency, which will reduce electricity demand to 2008 levels (accounting for around 1,000 terawatt hours/year. It also calls for a complete cessation of oil and coal for power generation (currently, coal provides around half of the electricity used in the US). Taking up the slack would be wind, solar, and geothermal power generation.

Wind power would grow from a current 16GW to 350GW, solar from 1GW to 250GW, and geothermal from 2.9GW to 80GW. These would be concentrated in the Great Plains, the southwest, and in offshore wind farms, placing power generation near population centers where energy consumption is highest.


Google's plan to transform US power generation by 2030

With regard to transportation, the report proposes almost logarithmic growth in plug-in hybrids, from 100,000 sales in 2010 to nearly 4 million by 2020, finally reaching 22 million by 2030. Coupled with measures to remove older, more-polluting, less-efficient cars from the roads, and an increase in fleet efficiency from 20 mpg now to 45 mpg in 2030, this would see a reduction in transportation-derived CO2 emissions of nearly 40 percent.

The overall effect of these proposed changes would be a reduction in annual US carbon emissions from a current 6 Gt/year to 3 Gt/year, which would take us halfway to the IPCC's 2050 CO2 target. Google also claims that implementation of this plan would realize significant savings to the economy in the range of $1 trillion over 22 years, coupled with the creation of more than a million new jobs building and operating wind turbines, solar panels, and associated fields.

The question of whether these are realistic aims probably depends upon the amount of political will to wean the nation off fossil fuels and toward renewable energy. Not that there aren't good arguments in favor of this being made from both ends of the political spectrum; Former CIA director and current McCain policy advisor James Woolsey gave a memorable and interesting talk on just this subject earlier this year, framing the need to move away from fossil fuel dependence in terms of national security rather than with an ecological bent, but it would be naïve to think that such measures wouldn't face opposition from entrenched business interests. The proposed shift away from fossil fuels will be vital though, should we wish to mitigate the more severe aspects of climate change.

7 Hurdles to Electronics Recycling

by Sarah Lozanova

If you are like most people, you have an old computer stuffed away in the back of your closet or an obsolete TV gathering dust in the corner of your garage. In many parts of the country, electronics recycling centers are few and far between and community-recycling drives are only offered once in a blue moon, if at all.

A staggering 400 million units of electronic waste are scrapped in the United States each year (International Association of Electronics Recyclers), and this trend is likely to continue, as there are always more gadgets to be had. Add to this the fact that electronics tend to become obsolete rather quickly, and you can see we have a growing e-waste problem.

“The electronics waste stream is growing at five times the rate of any other waste stream,” said Matthew Coz, VP of Growth and Commodity Sales for Waste Management Recycle America. “The product life cycles are shrinking. We are constantly creating more of that waste.”

Electronics recycling is the best way to respond to the issue in the short-term. It decreases the need to mine raw materials and keeps hazardous waste out of landfills. Recycling reduces greenhouse gas emissions and can create thousands of jobs. But the unfortunate truth is that only 12.5% of electronics are currently being collected for recycling, according to a 2005 EPA report. Of that quantity, much of it is not being safely handled.

With that said, there are numerous obstacles that need to be simultaneously addressed to bring about significant progress in the area of electronics recycling. The good news is that those obstacles are not insurmountable.

Improper Handling of Electronic Recycling

Not all electronic recycling programs are created equal, so it is important to exercise care when handing over those dusty, obsolete electronics. Although some recycling programs recycled nearly 100% of a given item, there is some truth to the stories about whole electronic items being shipped to developing countries where they are not properly handled or child labor practices may exacerbate health risks.

While some materials can be salvaged, often the remaining components are not safely handled. Electronics can contain large amounts of heavy metals such as lead and mercury, which can wreak havoc on the environment. Some of the main threats are air pollution from incineration or water contamination as hazardous materials break down and enter both surface water as well as groundwater supplies.

Such issues make effective legislation very important. In the meantime, the Basal Action Network has created an electronics recyclers pledge of true stewardship with a rigorous criteria for sustainable and socially just recycling practices (http://www.ban.org/pledge/Locations.html).

Policy

Although the European Union has had e-waste policies in effect since 2003, the U.S. lacks a coordinated national policy. Because of this lack in federal leadership, many individual states have taken the problem into their own hands by establishing state-level electronic waste programs.

“What has happened thus far is a state by state approach,” said Matthew Coz. “Right now there are roughly 19 states and NYC with e-waste legislation or a disposal ban on electronics. There are another 24 states with pending legislation.”

Policy can mandate responsible handling practices and restrict items from being dumped or improperly handled overseas. Having policy with some teeth can offer guidance to this fledgling industry and help establish much-needed infrastructure.

Infrastructure to Handle Growing Waste Stream

The transition from having 12.5% of electronics recycled to having the majority recycled will require a strong infrastructure, far beyond what is currently in place.

“We need facilities to be able to turn old plastics or old circuit boards into reusable materials that manufacturers can use,” said Garth Hickle, Director of Product Stewardship for the Minnesota Pollution Control Agency. “We are doing really well in the first tier of demanufacturing [electronics] into components, but we could use some more investment in the next step, like handling more value added processes such as plastics,” added Hickle.

Convenient Electronic Recycling

One of the easiest ways to engage consumers is by creating a network of convenient electronics recycling programs.

To wit, Sony and Waste Management Recycle America have recently teamed up to create a national electronics-recycling program, with drop-off sites in every state. Their goal is to have electronics recycling center within 20 miles of 95% of the U.S. population.

“We’re trying to make recycling as easy as it is to purchase,” said Doug Smith, Director of Environment for Sony Electronics. “Every pound we sell we want to take back and recycle a pound.”

“The reality is, the real solution comes when we have a couple thousand of these [drop-off] locations,” said Matthew Coz. “There is really a mosaic that needs to be built. We have to have other avenues besides just drop-off points.”

Other viable solutions for recycling of e-waste could include mail-in programs, community recycling drives, and retailer take-back programs. Although retailers have helped many European countries achieve high recycling rates, they have traditionally had little involvement in U.S. recycling efforts. Best Buy however recently started offering a free electronics-recycling program at 117 stores across the country.

Convenient recycling options also help reduce the environmental impact of transporting electronics. “If you have to get into your car and drive 60 miles to recycle a DVD player, from a carbon footprint perspective that is probably not a great solution,” said Matthew Coz.

Making Electronic Recycling Lucrative

In an ideal world, electronics will be recycled because of the economic benefits and that is true to some extent today.

“There are some valuable materials in electronics, such as aluminum and copper,” said Garth Hickle. “Given the global commodity prices for those materials, there really is some economic benefit to recycling. Oil is currently priced at $147 a barrel, making plastics in some products more valuable.”

If the cost of metals and plastics increase, the recycling market will benefit. As the scale of recycling programs expands, the costs associated with recycling will diminish. Advances in product design will make recycling easier and more cost effective. Improving the recycling infrastructure will decrease the need to transport materials long distances and provide more uses for recycled materials.

Manufacturer Responsibility and Product Design

Designing electronics that can be easily recycled will be a breath of fresh air to recyclers and will make recycling more lucrative. This can be achieved by placing responsibility on the producer (manufacturers and importers).

“If manufacturers are responsible for recycling, there is a defined incentive both from a liability and financial perspective for them to make sure those products can be more easily and thus more cheaply recycled,” said Garth Hickle.

Product design is an area that can be greatly improved, especially when considering the reuse of product components. Reducing the use of hazardous materials and producing electronics that can be easily dismantled is one method of accomplishing this. Using fewer plastic resins and the use of screws instead of glue for example helps streamline the recycling process.

Ultimately, recycling is not a long-term solution to the ever-increasing e-waste stream and a paradigm shift is needed. Remanufacturing is one such example and involves making today’s gadget using yesterday’s parts. Such products come with enhancements over the old product and a fresh warranty. For example, a paper tray in a copy machine being manufactured today can have a paper tray that is compatible with models from previous years. The paper trays in good condition from recycled copy machines can be reused instead of recycled. Xerox Europe has been very successful at doing this and diverted 170 million pounds of waste from landfills in 2007 alone.

Remanufacturing is the best-case scenario because it saves both energy and raw materials, beyond what recycling can offer. Although cost savings to the manufacturer can be significant, it does require considerable attention in the design of a product and it is more labor intensive to dismantle rather than recycle electronic appliances. Remanufacturing is usually best suited for products that are not evolving so quickly, such as vacuum cleaners rather than flat screen TVs or cell phones.

Collaboration and Partnerships

All hands are needed on deck to tackle the issue of electronic waste. Alliances among companies and organizations in various industries are helpful. Sony and Waste Management formed a partnership and a national electronics-recycling program where nearly 100% of a given product is recycled - a program that would have been very difficult for one company to create alone.

Corporations purchasing large quantities of computers can work with the manufacturer to ensure that the products will be safely recycled or refurbished at the end of product life. Community and church groups can host recycling drives, while schools can educate students on the importance of recycling. Refurbishers offer a great service by avoiding the need to recycle items, while decreasing the need for new gadgets. Goodwill and other thrift stores have done this effectively for years.

The scope, urgency, and complexity of the situation demands an assortment of solutions and approaches. The most effective advances depend on companies, organizations, and local governments coming together to create convenient ways for individuals to recycle their electronic waste.

Offshore Wind To Supply 15% of Rhode Island Electricity

Rhode Island took a step toward reaching its goal of providing 15% of its electricity from wind power, when it awarded Deepwater Wind the contract to build a $1 billion+ offshore wind farm.

Rhode Island Gov. Donald Carcieri touted the project's potential to bring "green collar" jobs to the state, and position it as a leader in an emerging clean energy technology. Indeed, part of the deal includes a provision that the company build a $1.5 billion manufacturing plant in Rhode Island that promises 800 jobs at an average annual salary of $60 million.

While wind power produces only 1% of U.S. electricity today, some estimate it could produce as much as 20% by 2030. And, coupled with conservation -- the largest single untapped source of future energy -- wind can be an important piece of the American energy puzzle in a low-carbon future.

Rhode Island is among the states to have set a renewable energy portfolio mandate that 20% of electricity come from renewable sources by 2020. Federal lawmakers have resisted a similar national mandate, though setting that priority surely contributed to the viability of Rhode Island's offshore wind project. Barack Obama's energy plan includes a mandate that utilities generate 25% of electricity from renewable sources by 2025. John McCain has offshore oil as a centerpiece of his energy plan, and his support for renewable energy sources is largely rhetorical and shorter on specifics.
