Utilities prepare to open natural gas pipes to biogas - 0 views

  •  
    I have a story today on Enbridge Gas Distribution and its early investigation of biogas-injection into its natural gas pipelines. It's already being done in several European countries and some U.S. states, and is even mandated in countries such as Germany. Enbridge, and Terasen Gas in British Columbia, are among a number of gas utilities in North America that are trying to prepare themselves for the day when "bio-methane" will become a common component of natural gas pipeline infrastructure. Will the biogas quality affect the pipeline? Can it be used in all natural gas appliances without problem? How much does it cost to scrub out impurities? What's the best source: landfills, sewage treatment plants, biodigesters? All questions that are being asked and answered. Indeed, the Gas Technology Institute is in the middle of a $1.6 million (U.S.) study aimed as answering these questions.

The American Spectator : A True Energy Policy - 0 views

    Excellent over view of shale gas and compressed natural gas dynamics including conversion kits for automobiles and truck fleets. THE ONLY LOGICAL ANSWER to bridge the conversion from oil based fuels to paradigm alternatives lies in the conversion of personal transportation to the use of natural gas. Consider the following reasons: (long list) ONE WEEK AFTER Obama's energy policy speech, March 31, 2011, at Georgetown University, a bi-partisan group of more than 150 Members of Congress introduced HR.1835, with Rep. John Sullivan (R-OK) as the primary sponsor. The NAT GAS Act (New Alternative Transportation to Give Americans Solutions) Act, is the culmination of efforts of T. Boone Pickens to promote his "Pickens Plan" for changing the focus of American energy consumption. The NAT GAS Act provides incentives for using natural gas in vehicles, purchasing natural gas vehicles, installing natural gas refueling stations, and producing natural gas vehicles in America. The problem is that Obama and his energy secretary do not actually support HR 1835!  The speech was just a ruse.  Watch what he does, not what he says.  CNG-Compressed Natural Gas

Could Cheap Natural Gas Slow Growth Of Renewable Energy? : NPR - 0 views

  • The boom in cheap natural gas in this country is good news for the environment, because relatively clean gas is replacing dirty coal-fired power plants. But in the long run, cheap natural gas could slow the growth of even cleaner sources of energy, such as wind and solar power.

Biofuels: indirect land use change and climate impact - 0 views

  •  
    "The objective of this study is to:  compile the available recent literature on ILUC emissions;  compare these emissions with the assumed gains of biofuels;  assess how ILUC changes the carbon balance of using biofuels;  formulate policies to avoid these extra emissions associated with ILUC. Trends in land use, with and without biofuels All the studies on global agricultural markets reviewed predict that new arable land will be required to meet future global demand for food and feed. Although there will be increased productivity on current arable land (intensification), food and feed demand will probably grow faster, which means that mobilization of new land is likely to occur. Biofuels produced from crops (the current mainstream practice) will add extra demand for crops like wheat, rice, maize, rapeseed and palm oil. This will increase prices for these crops (as well as for land) and lead to two impacts: intensification of agricultural production and conversion of forests and grasslands to arable land. In this report we consider the issue of indirect land use change initiated by EU biofuels policy and seek to answer the following questions:  What is the probability of biofuels policies initiating land use changes?  What greenhouse gas emissions may result from indirect land use change, expressed as a factor in the mathematical relation given above?  What technical measures can be applied and what policy measures adopted to limit or entirely mitigate indirect land use change and the associated greenhouse gas emissions? We first (Chapter 2) broadly discuss the mechanism of indirect land use change. We next discuss why there is a perception among stakeholders that there is a serious risk that EU biofuels policy will initiate indirect land use change (Chapter 3) and consider the figures cited by other studies as an indication of the magnitude the associated greenhouse gas emissions  (Chapter 4). We then broadly consid

Global greenhouse gas emissions accelerate rise - 0 views

  •  
    The Emission Database for Global Atmospheric Research (EDGAR) found that global annual emissions of greenhouse gases totalled 41 billion tonnes in 2005, up from 24 billion tonnes in 1970 and 33 billion tonnes in 1990. Between 1990 and 2005, total greenhouse gas emissions amounted to 560 billion tonnes. The EDGAR dataset shows that greenhouse gas emissions have been higher in developing countries than in industrialised countries since 2004, though developing countries emit significantly lower levels of emissions per capita than developed countries (4 tonnes, versus approximately 15 tonnes).

Energy Efficiency, Natural Gas and Renewable Energy Drove Decade of U.S. Energy Transfo... - 1 views

  • The 2020 Factbook showcases the impact of sustainable energy over the last decade and highlights findings for 2019 that follow the macro trends of the 2010s: • Renewable energy became the cheapest new generation source in many U.S. power markets. The U.S. has over 2 times more renewable power generating capacity today than a decade ago. Solar capacity in 2019 was 80 times greater than what it was at the end of 2009. • Energy efficiency choices have proliferated, with federal programs helping high-efficiency appliances reach mass markets and state codes bolstering building efficiency. The economy grew every year in the past decade and energy use fell in five of the ten years. U.S. energy productivity (GDP/energy consumption) improved 18% between 2010 and 2019, benefiting businesses and households. • Natural gas became the primary source of U.S. power generation and shifted the scales in the global market. Between 2010 and 2019 domestic natural gas production jumped 50%, and natural gas went from providing 24% of the nation's electricity to 38%. The U.S. increased its export capacity to exceed its import capacity, building stronger trade relationships around the world. In 2019, the U.S. exported more gas than it imported.

  • OECD European gas production looks set to peak in 2008. After that, falling production combined with rising demand will see OECD European gas imports wanting to rise from current 197 BCM per annum to 442 BCM per annum by 2020. Where will this gas come from and how will rising European imports affect N America and the rest of the world?

ApplianceMagazine.com | Sustainability in Home Appliances - Europe Report - 0 views

  • The buzzword these days is sustainability. A few years ago, this meant responsibility in a broader sense. Now, the focus is more on actual products. So, which alternatives can the industry offer to the appliance industry’s well-known products? And are these actually large, revolutionary steps? In white-good appliances, there are several alternatives. Europeans switched to high-efficiency horizontal-drum washers a long time ago—a revolutionary technology that left little room for improvement. The next big step might be to heat the water with gas instead of electricity. Martin Elektrotechnik is one German company that offers an automatic external water selector. It detects activation of the heating element and switches accordingly. However, at 285 euros, sales have been limited. The same unit can also be used for the dishwasher. The clothes dryer is another story. These appliances use 3–4 kWh per run, and there are more-efficient alternatives—the gas dryer and the heat pump dryer. Europe has a few gas dryer manufacturers, including UK-based Crosslee with its White Knight brand and Miele. Despite the advantages of efficiency and shorter drying time, they have not caught on in the larger marketplace. They only come as vented units, not as condenser units, and connecting the gas is just too much of a hurdle for many consumers, even when there is a click-on gas connector system available. Heat pump dryers are relatively new. Electrolux started in 1997 with an almost hand-built model under their premium, environmentally oriented AEG brand. At a price point of 1500 euros, even wealthy German consumers would not buy many of them. In 2005, the company started selling a redesigned model, called Öko-Lavatherm. It claimed energy savings up to 40% for around 700 euros, which is more in line with the cost of other premium models. Other manufacturers of heat pump dryers include Blomberg, the German brand owned by Turkish market leader Arçelik, and Swiss Schulthess. In cooling, there have been no large breakthroughs. Years ago, there was talk of vacuum-insulated panels, but no models were produced. Instead, there have been a number of smaller-scale efficiency improvements, and today, the industry suggests that consumers simply buy new, extraefficient models. AEG offers a typical case: a 300-L cooler/freezer in the A++ efficiency class now uses only 200 kWh per year, whereas a 10-year-old model used as much as 500 kWh. And what about the heating industry? Remember that in chilly Europe, heating is the largest energy user. The advice here is almost the same as for white-good appliances—just replace old equipment. There are still many noncondenser boilers on the market and a significant percentage of houses are insufficiently insulated. German Vaillant is calling its efficiency initiative "Generation Efficiency." But, like the home appliances market, progress is gradual. Current boilers are already highly efficient. Other technologies, such as solar panels, combined heat-and-power units, and heat pumps, catch on more slowly. Still, there were 1.1 million renewable energy units sold in Europe in 2006 compared with 440,000 just two years earlier. Some of the company’s smaller steps forward were seen at ISH. The small Vaillant ecoCOMPACT combiboiler now has a high-efficiency pump, which is said to reduce electricity use by 50%. Hot water output is higher for user comfort, and there are new modules for remote access for better preventive service. The main obstacle for customers wanting a heat pump is the installation, as sometimes complex drilling is needed. Vaillant solved that issue by taking over a drilling company and offers all of the services for a fixed price, just like its competitor, BBT Thermotechnik. Across the board, it seems manufacturers continue their efforts toward sustainability. The question now seems to be whether or not consumers will take advantage of the technology.

Greenhouse gas could become clean fuel - 22 April 2009 - New Scientist - 0 views

  •  
    CONVERTING a greenhouse gas into a clean-burning fuel offers two benefits for the price of one. That's the thinking behind a novel process for converting carbon dioxide into methanol at room temperature, developed by a team at the Institute of Bioengineering and Nanotechnology in Singapore (Angewandte Chemie International Edition, DOI: 10.1002/anie.200806058).

Cooking - gas or electric - 0 views

  •  
    Among the major culprits here are inefficient appliances. According to the United States Department of Energy, a gas burner delivers only 35 to 40 percent of its heat energy to the pan; a standard electrical element conveys about 70 percent. Anyone thinking about kitchen renovation should know that induction cooktops, which generate heat directly within the pan itself, are around 90 percent efficient.

The Oil Drum | The National Petroleum Council Report - 0 views

  • Ok, so we're asking the oil and gas industry, who make their living by selling us oil and gas, whether there might any problem with the supply of oil and gas. I don't know what Secretary Bodman was expecting, but in his place I would have expected to get a sales pitch for buying more oil and gas. Given that very low expectation, the report is better than one might have feared.

The Energy Blog: Natural Gas Civic Beats Prius - 0 views

  •  
    Honda's natural gas Civic GX, which debuted in 2006 in California but is now becoming available in other parts of the country, just may be the cleanest mainstream car on the road. At least the American Council for an Energy-Efficient Economy (ACEEE) thinks so. The nonprofit group . . . put the Civic GX at the top of its 2007 environmentally friendly car list, edging out Toyota's hybrid Prius. The natural gas-fueled Civic scored slightly better than the Prius on fuel economy and reduced emissions in ACEEE's battery of tests. It also scored better in terms of the pollution generated in the manufacturing processes.

Electricity | Pew Center on Global Climate Change - 3 views

    The electricity sector accounts for almost 35 percent of greenhouse gas (GHG) emissions in the United States, and 40 percent of the carbon dioxide (CO2) emissions. Over 80 percent of GHG emissions associated with electricity generation are from the combustion of coal, with nearly all the rest due to natural gas and petroleum combustion. U.S. electricity sales are split among the residential (37 percent), commercial (36 percent), and industrial (27 percent) sectors, where primary uses vary by sector. Over the past 30 years the U.S. electricity sector has become less carbon intensive, and the U.S. economy has grown less electricity-intensive.

A Better Way to Make Fuel from Solar Energy | MIT Technology Review - 1 views

  • Burning natural gas emits about half as much carbon dioxide as burning coal, but it still produces large amounts of the greenhouse gas in the atmosphere. A novel device being developed at the Pacific Northwest National Laboratory (PNNL) could reduce those emissions by 20 percent by using heat from the sun to convert natural gas to an alternative fuel called syngas, a lower carbon fuel.

Metrics - Wasted Energy - NYTimes.com - 0 views

  •  
    It's gone before you even knew it was there: As energy is unlocked from fuels at power plants, two-thirds of the energy consumed to create electricity is lost. The laws of thermodynamics dictate that conversion efficiency will never be 100 percent, because heat is lost at every step of the conversion process. But new technologies may be able to greatly increase conversion efficiency, moving from an overall rate of 36 percent to closer to 50 percent. At present, coal - in all its carbon-belching inefficiency - is king because it's cheap. Still, the use of natural gas to create electricity has been rising rapidly, in part because of more-efficient gas turbines. Natural gas prices have been climbing, however, and coal prices could rise as well.
