RENEWABLE ENERGY: Study: Six east coast states could replace dirty fossil fuels with clean energy derived from offshore wind

As the United States struggles to do the right thing in terms of energy policy, the United Kingdom has just switched on the world’s largest offshore wind farm, which consists of “100 turbines spreading over 35 square kilometers, or 13.5 square miles, with a capacity to power more than 200,000 homes.” Also, Danish energy policy is pushing Denmark to be fossil fuel-free by 2050. China is also surpassing the United States in offshore wind development: “Chinese energy companies are expected to submit bids Friday for four offshore wind power projects with a total installed capacity of 1,000 megawatts, representing a combined investment of $3.06 billion.”

As the world population continues to grow and expand, energy demand and energy prices will continue to rise, as nonrenewable energy sources such as oil and coal are depleted. Rising energy prices helped trigger the economic downturn in the United States, so the United States government must protect its economy by aggressively implementing prudent energy policies, which are working in other countries.

More on the east coast’s renewable energy potential via the‎ International Business Times:

Oceana, compared the costs of offshore wind energy with oil and gas. The study focused primarily on the east coast and concluded an investment into wind energy would create jobs, reduce pollution and in many cases create just as much energy as fossil fuels.

All told, Oceana concluded wind energy could produce 30 percent more electricity than economically recoverable offshore oil and gas on the east coast. The group said the investment it proposed would supply nearly half of the current electricity generation of East Coast states. Oceana used conservative estimates of potential ocean spaces for wind farms.

.       .       .

In six states: Massachusetts, North Carolina, Delaware, New Jersey, Virginia and South Carolina, Oceana said wind energy could completely replace fossil fuels. In the first three states, it would completely reduce the need for any fossil fuels. In the latter three, it at least would replace the energy demand. In some states, energy is exported to other states.

CONSERVATION: Hunters, rich conservationists, and local farmers can help protect Africa’s wildlife

[N]o matter how fecund nature is, humans are more so. With Africa’s human population set to double to 2 billion by 2050, new thinking is needed to preserve the continent’s remaining biodiversity.

Image: In order to protect the last remaining northern white rhinos (Ceratotherium simum cottoni) from poachers, conservationists must keep their horns filed down. Although “a slight recovery was recorded in 2003[,] when 30 [northern white rhinos] were counted[,] . . . by 2006 only four were left.” After the rhino’s last known stronghold—the Garamba National Park in the Democratic Republic of Congo—succumb to war and civil unrest, the remaining northern white rhinos haven’t been seen since. The individual below represents captive individuals that were translocated to Ol Pejeta in order to improve their fecundity. Image via Wikipedia

The Economist has an interesting piece on how economics can be a major driver of species extinctions—particularly when demand and value are high for animals or certain type of animal parts (e.g., poaching for medicinal purposes or poaching live specimens for the pet trade). The article begins by giving a somber assessment of the northern white rhino.
Certainly, if economics can destroy nature, then economics can also be used to save nature. For example, hunting is “a potential bonanza for local communities.” Therefore, as a product of that idea, the authors mention that anti-hunting efforts may hurt conservation efforts. The article also highlights another problem facing conservation efforts—human expansion—and briefly mentions how culture can be a factor in accelerating biodiversity loss, which is an interesting idea.

To save species, particularly in Africa, the authors don’t necessarily promote the fortress model towards conservation, but they offer several alternative ideas that seem to have success or potential for success. For example, (1) conservationists should place value on biodiversity; (2) the management of Africa’s national parks should be modernized; (3) the privatization of land through wealthy conservationists, local communities (i.e., community-based conservation), or organizations, with access to adequate resources (e.g., monetary, indigenous knowledge, international donors), may be successful at conserving wildlife and landscapes; (4) employing “‘non-use’ earnings, where large numbers of people around the world pay small sums to buy shares in African biodiversity not to use it, but simply because they believe its protection is important to the planet, may achieve conservation goals; (5) addressing social issues such as poverty, illiteracy, and alcoholism can reduce pressure on natural resources; and (6) “looking at wildlife, rather than shooting it” can be a model for successful conservation. Of course, the idea of sustainability looms over all of these ideas.

There’s another issue at play, and it’s more of a philosophical consideration, but it raises important questions nonetheless. Even if hunting, or any other type of wildlife management scheme can successfully boost wildlife numbers or achieve conservation goals, then humans are undoubtedly creating nature or merely socially constructing nature. Consequently, we’re not saving the wilderness as it’s typically idealized in our minds or the first nature before humans (it’s impossible to know what that exactly looks like). We’re either saving what we think nature and wilderness should be or we’re shaping nature, wilderness, landscapes, or ecosystems to better fit our agenda. Essentially, the ideas we determine are fit to achieve conservation goals will paint the picture of nature or have a direct impact on the “natural” landscape. Perhaps, chewing over the idea of a socially constructed nature when considering conservation goals is meaningless, since nature has been, and will continue to be, socially constructed. Via The Economist (emphasis added):

ONLY eight specimens of the northern white rhino are left alive on the planet, and they are all in captivity. The handful that remained in the wild in Congo have not been seen in years; they are almost certainly dead. A final effort to save the sub-species earlier this year saw four northern whites shipped from a zoo in the Czech Republic to the Ol Pejeta conservancy on the Laikipia reserve in Kenya.

.       .       .

[T]he chances of saving the northern white are remote. Short of re-engineering it from frozen samples in the future, the best hope of preserving its genetic stock is to breed the last individuals with southern whites. That means the end of a creature that has probably been distinct for a million years. Indeed, the decline of the African rhino—which includes the black rhino as well as the white—is among the sorriest and most instructive tales in conservation.

When President Theodore Roosevelt came to east Africa in 1909 an estimated 300,000 rhinos roamed the region. Now there are perhaps 2,000. The problem is not that the rhinos are half-blind, lumbering, and often infertile—which they are. It is economic: the ornamental and medicinal value of rhino horn makes it hard for the rhino to pay its way alive.

The value of rhino horn in China, ounce for ounce, is higher than gold. It is likely to keep rising with an ageing population; in Chinese medicine the horn is ground into a powder to alleviate fevers and pain, particularly for terminally ill patients. With more Chinese contractors working in Africa, the risk of poaching seems to have increased. Market forces are insistent. Even at Ol Pejeta, which is protected by electric fences and armed guards, the horns of the four northern whites have had to be filed down to limit the risk of poaching. An inside job at one private ranch in Kenya last Christmas saw a rhino killed and its horns hacked off. The Kenya Wildlife Service later tracked down the culprits and recovered the horns, along with $8,500 in cash the poachers had been paid, with the balance payable on delivery. Sold in 10g increments in Guangzhou, the seven kilos of horn would be worth $250,000.

.       .       .

Some countries have had success with hunting. Namibia, for instance, has increased the absolute numbers of its game animals by allowing oryx, hartebeest, kudu and springbok to be hunted and harvested as high-protein low-fat meat for regional supermarkets. Peter Lindsey of the University of Pretoria argues that animal-rights groups are denying Africa the wise use of its elephants—whose ivory is a resource, in his view, because elephants’ fertility suggests it could be harvested sustainably. He reckons trophy-hunting in Africa is worth $200m a year: a potential bonanza for local communities.

But animal-rights organisations like the Born Free Foundation object to hunting on ethical grounds. They argue that many hunters who start with gazelles end up going after predators, often illegally. And the money does not reach the locals: much of what is generated is taken offshore. The debate is bitter. The pro-hunting lobby complains that animal-righters have a lot of money to splash around, and are even writing legislation in several African countries in return for donations to government wildlife services. Hunters say their activities complement tourism: their clients are happy to stay in shabby, dusty places as long as they get their kill. But the bloodthirsty history of big-game hunting in Africa means that hunters still need to show that they have an economic value.

PEAK OIL: LOL OIL

LOL @ society for supporting politicians, policies, and lifestyles that reinforce our addiction to oil—a nonrenewable resource. Our delayed reaction to our predicament and continued apathy towards change reminds me of the Aesop fable—The Grasshopper and the Ants.

ACID RAIN is increasing

Image via numbphoto – Color mad on Flickr

Acid rain is an environmental problem, because it destroys forests and aquatic ecosystems. More from the U.S. Environmental Protection Agency:

Acid rain causes acidification of lakes and streams and contributes to the damage of trees at high elevations (for example, red spruce trees above 2,000 feet) and many sensitive forest soils. In addition, acid rain accelerates the decay of building materials and paints, including irreplaceable buildings, statues, and sculptures that are part of our nation’s cultural heritage. Prior to falling to the earth, sulfur dioxide (SO2) and nitrogen oxide (NOx) gases and their particulate matter derivatives—sulfates and nitrates—contribute to visibility degradation and harm public health.

Emissions of sulfur dioxide and nitrogen oxides from utilities contribute to the problem of acid rain. However, emissions trading or cap and trade, a market-based regulatory program, which is also “a program within the 1990 Clean Air Act Amendments,” was successful in reducing these pollutants. As a result, the Acid Rain Program was successful in reducing acid rain. However, an increase in other types of anthropogenic activities is contributing to the problem of acid rain. For example, industrial agriculture operations, such as concentrated animal feeding operations, or CAFOs, also contribute to acid rain. Other factors for the return of acid rain include agricultural nitrogen runoff and more vehicles, which are displacing the gains made from the introduction of the catalytic converter. More from Scientific American:

The acid rain scourge of the ’70s and ’80s that killed trees and fish and even dissolved parts of statues on Washington, D.C.’s National Mall is back. But unlike the first round, in which sulfur emissions from power plants mixed with rain to create sulfuric acid, the current problem stems primarily from nitrogen emissions mixed with rain to create nitric acid.

.       .       .

Sulfur emissions from power plants were one of the primary motivations for the U.S.’s Clean Air Act Amendments of 1990, which set reduction targets for both sulfur dioxide (SO2) and nitrogen oxides (NOx). However, whereas sulfur dioxide emissions decreased almost 70 percent from 1990 to 2008, emissions of one NOx—nitrogen dioxide (NO2)—went down only 35 percent for that same period, and amendment targets have yet to be made, according to the U.S. Environmental Protection Agency (EPA). “This comes as scientists have grown increasingly aware of the consequences of the remaining nitric acid deposition,” Schlesinger says.

.       .       .

Nitric acid rain is derived primarily from power plant, car and truck emissions as well as from gases released by fertilizer use. Part of the problem dates back to WWI, when two German scientists invented the Haber–Bosch process, which took nonreactive nitrogen from the air (N2) and converted it into reactive, usable ammonia (NH3). Most of the nitrogen harvested via this process has been used in fertilizers, and the runoff from farms has created dead zones in Chesapeake Bay and at the mouths of the Columbia and Mississippi rivers. Some efforts have been made to regulate the agricultural nitrogen runoff, but atmospheric emissions of agricultural ammonia remain virtually unrestricted.

Agri-ammonia vapors also derive from concentrated animal feeding operations in the U.S. South. The gas rises into the air and is deposited dry or in rainfall where in the ground bacteria breaks it into nitrogen and nitric acid, which can kill fish and plants. “Agriculture is increasingly functioning as an intensively managed industrial operation, and that is creating serious water, soil, and air problems,” says Viney Aneja, a professor at North Carolina State University in Raleigh. Aneja says that state’s concentrated animal feeding operations may also emit particulate matter from swine and chicken manure into the atmosphere, which can carry diseases.

NOx escapes from power plants as a by-product of coal combustion, whereas vehicular engines run at high enough pressures and temperatures to combine nitrogen and oxygen in the air. “Though catalytic converters have decreased the amount of pollution per vehicle, there are more vehicles on the road and more miles driven,” Schlesinger says. Emissions from fertilizers are the chief source of atmospheric nitric oxide, but motor vehicles have now overtaken coal power plants as the secondary most critical source of this problem.
