Renewable Fuels for Alternative Strength

Atala — Thu, 15 Jul 2010 04:18:22 +0000

The Germans have truly taken off when it comes to green fuel sources, and have become one on the significant players from the option energy game. Under the aegis in the nation’s electrical power feed laws, the German folks set a world record in 2006 by investing above $10 billion (US) in investigation, improvement, and implementation of wind turbines, biogas power plants, and solar collection cells. Germany’s “feed laws” permit the German homeowners to connect to an electrical grid via some source of renewable strength and then sell back on the power organization any excess energy produced at retail prices. This economic incentive has catapulted Germany into the number-one position among all nations with regards towards the quantity of operational solar arrays, biogas plants, and wind turbines. The 50-terawatt hours of electrical energy produced by these renewable vigor sources account for 10% of all of Germany’s power production per year. In 2006 alone, Germany installed 100,000 solar power collection systems.

Over in the US, the BP corporation has established an Strength Biosciences Institute (EBI) to spearhead extensive new study and development efforts into clean burning green energy sources, most prominently biofuels for ground vehicles. BP’s investment comes to $50 million (US) per year more than the course from the next decade. This EBI will likely be physically located at the University of Illinois Urbana-Champaign. The University is in partnership with BP, and it will be responsible for study and development of new biofuel crops, biofuel-delivering agricultural systems, and machines to generate green fuels in liquid form for automobile consumption. The University will particularly spearhead efforts inside field of genetic engineering with regard to creating the far more advanced biofuel crops. The EBI will additionally have as a important focal point technological innovations for converting heavy hydrocarbons into pollution-free and extremely efficient fuels.

Also inside US, the battle rages on between Congress and also the Geothermal Strength Association (GEA). The GEA’s Executive Director Karl Gawell has recently written towards the Congress as well as the Department of Energy, the only way to ensure that DOE and OMB don’t simply revert to their irrational insistence on terminating the geothermal investigation program is to schedule a congressional hearing specifically on geothermal strength, its potential, as well as the role of federal study. Furthermore, Gawell goes on to say that recent studies by the National Study Council, the Western Governors’ Association Clean Vitality Task Force and also the Massachusetts Institute of Technology all support expanding geothermal analysis funding to develop the technology necessary to utilize this vast, untapped domestic renewable power resource. Supporters of geothermal power, for instance this writer, are amazed at the minuscule amount of awareness that the public has about the huge advantages that exploration and advancement from the renewable option strength source would provide the US, both practically and economically. Geothermal vigor is already less costly to create in terms of kilowatt-hours than the coal that the US keeps mining. Geothermal strength is readily offered, sitting just a few miles below our feet and simply accessible by way of drilling. A single company, Ormat, which is the third largest geothermal power producer in the US and has plants in several several nations, is already a billion-dollar-per-year business-geothermal vigor is certainly economically viable.

The Best Facts About Solar Energy

Atala — Thu, 15 Jul 2010 04:08:17 +0000

Facts about solar energy help you to understand how solar energy works and how you can save some dollars without having to run a high energy bill. Solar energy is a inexhaustible resource and of the oldest method of energy use that is available at nowadays. The important fact about solar energy is that the sun s rays are so powerful that if we are to convert that into energy it would mean that Earth will never run out of energy for at least another four point five billion years according to scientists. The sun does not create any other hazardous by products which could harm the natural environment.

During the early fifties solar energy was looked upon as an substitute to man made energy resources. Over some research it was found energy could be acquired at some cheaper source. The demand for solar energy has grown substantially within the range of 20-25% over the last twenty years. Solar energy is able to support home appliances, lighting and water heaters. As of the minute, solar energy is more heavy priced but in the near future with the increase in technological studies, it will bring down the costs and also growth its efficiency. By 2025, it is expected to generate 2.5% of the world energy demand through solar energy. Solar energy can be considered as the fastest growing technology.

There are some fundamental facts about solar energy that one needs to be presented to; solar energy is measured in kilowatt hours and 1 kilowatt=100 watts. One kilowatt hour is equal to the amount of electricity which is wanted to burn 100 watt light bulb for approximately 10 hours. 866 kilowatt is the consumption by an average American household. The Residential Energy consumption Survey conducted in 2001 shows that an annual energy bill was around $2000.

A reduction in unit costs has added towards an growth in growth rates and thereby making it an critical energy resource. After year 2000, solar energy has shown a growth rate of 40% per annum. Solar energy is moving at a increasing rate in the developing countries too as the use of fossil fuel has doubled over the years. When compared to solar energy which is unlimited, fossil fuel reserves are decreasing. Setting up solar energy appliances is relatively easier in the more remote areas in comparison for setting up an expensive power grid structure. A disadvantage of fossil fuels is that the prices have risen together with the price of transporting coal, oil and gas. These are just a couple of the facts about solar energy.

What to Know in Residential Wind Turbines

Atala — Wed, 14 Jul 2010 07:58:15 +0000

When you think about wind turbines, the tower with four blades reminiscent of Holland country landscape with the tulips and the Dutch gal is the first image that may come to mind. That image of a windmill seems a prototype of the mechanical wind turbine, also called aerogenerator that uses the wind energy to turn kinetic energy to electricity. It is also one of the mechanical inventions requiring great respect for it helps in alleviating the over-dependence of fossil fuels in generating electricity to power homes.

A distinction is to bring regards though in associating windmill with wind turbines. Windmill has mechanical purposes and that may not include generating electricity. The wind turbines, however, are invented to harness the strength of the wind to convert energy to electricity by turning the blades of the electric-generating wind system.

It may not be necessarily that huge to construct one unless you want megawatts of electricity to power a lot of machines in many households; that situation may need a behemoth one or numerous wind turbines beautifully lined up on a road or isolated locations to bring electricity to a whole town or a district of towns. The wind turbines may be humongous but seeing them collectively in an orderly, interval set-up makes them like the 8th modern wonders. These turbines have been utilized as a gradual replacement to the fossil fuels.

However, in the case of wind turbines for domestic application, the towering machines don’t have to be that big. A certain size for home use may be installed though. But, it is also important to note how much electricity you normally consume, as this will be a factor in availing a residential wind turbine with the appropriate capacity of the system for use in homes.

There are some things to learn about residential wind turbines. Although aerogenerator can be among the best machines that help lessen the amount of smokes fumed out from the power facility, using this at home is in simultaneous fashion with procuring electricity from local power utility at the beginning. The cut-in speed of wind turbines for homes is 7-10 mph. Below that speed is not sufficient to power a home, so it is better to have another connection of wires with electric power derived from the local power utility plant.

However, when the wind speed peaks up in the location of the wind system, enabling the turbine to roll its blades faster, the energy piles up converting to electrically charged current. As the turbine’s blades move at faster rotating speed and continuously, more and more electric current is made and the electricity may be enough to power homes, thus decreasing or eventually eliminating the dependence of power from the local power retailer. There can also be the tendency that the excess power produced from the turbine can be sold to the local power utility.

Residential wind turbine is an alternative medium to obtain energy to turn into electricity to power homes. This can be used as replacement to or in conjunction with solar panels, making your home environmentally friendly. This blade-turning machine with rotor and shaft may not even require batteries to make it work. Modern residential wind system eliminates the need for batteries and this is to watch out for when opting to acquire one or a set of required wind system.

If you desire to have a set of the wind machine system that helps generate electricity in your homes, make it a point to browse around. The best deals of residential wind turbines are just here for your purchasing decision.

State Policy Options for Utility-Scale Wind Plants

Atala — Sun, 11 Jul 2010 11:57:05 +0000

Ryan Wiser and Mark Bolinger, Berkeley Lab

Although dramatic cost reductions have allowed wind power to become the least-cost energy option in some regions of the United States, state policies still play an essential role in stimulating wind power development in most areas. The range of available policy options for large-scale wind projects is broad. Some of the prominent state-level approaches used in the past to promote wind power include renewable energy purchase mandates, renewable energy funds, tax incentives, resource planning, and environmental credit markets. Each of these options, along with its advantages and disadvantages, is briefly described below.

Renewable Energy Purchase Mandates

Renewable energy purchase mandates include traditional set asides directed at individual utilities in a regulated setting and renewables portfolio standards (RPS) that require all retail suppliers to serve a minimum portion or their load with eligible renewable energy. Examples of traditional purchase mandates can be found in Iowa and Minnesota. In Iowa, certain in-state investor-owned utilities are required to develop 105 average megawatts (MW) of eligible renewables. In Minnesota, Northern States Power (now Xcel Energy) is required to develop 425 MW of wind by 2002 and another 400 MW by 2012 as part of a radioactive waste settlement agreement. Meanwhile, 11 states—Arizona, California, Connecticut, Maine, Massachusetts, New Jersey, New Mexico, Nevada, Pennsylvania, Texas, and Wisconsin—have enacted some form of RPS. Of all the state policy types discussed here, renewable energy purchase mandates will likely have the largest impact on wind development. Set-asides and RPS policies are attractive in some states because they create a strong demand for wind generated electricity, offer incentives for wind power cost minimization through a competitive process, can be used in regulated and restructured market settings, and rely on the private market to make renewable energy investment decisions. In other states, however, political considerations make purchase mandates difficult to implement in legislatures. In states where politics allow the creation of RPS policies, the policies must be designed carefully to have the desired effect. Experience shows that effective RPS policies in restructured markets require a strong level of political support and regulatory commitment, clear and well-thought-out renewable energy eligibility rules, predictable long-term renewable energy targets that ensure new wind power supply, standards that are achievable given permitting and transmission challenges, credible and automatic enforcement, and credit-worthy electricity suppliers that are in a position to enter into long-term contracts with renewable energy generators. Texas is typically identified as the “model” for an effective RPS. The design of an RPS policy is typically easier in a regulated setting than in a competitive setting. The key issues should focus on utility cost recovery and standardized power-purchase contract terms.

Renewable Energy Funds

Most often funded through system-benefits charges (a small surcharge on electricity rates) but occasionally through regulatory or merger settlements, state renewable energy funds provide major support for utility-scale wind development. Present in 15 states (most are restructured), these funds are expected to generate $3.5 billion for the development of renewables from 1998 through 2012. Production incentives (cents/kWh supplemental financial payments) are the most common form of incentive employed by renewable energy funds in support of utility-scale wind power, although up-front grants, forgivable loans, and subordinated debt have also been used. To date, nine states have obligated $160 million to support 1,630 MW of new wind power. As of the date of this publication, 148 MW had been installed. Several lessons have been learned from experience with renewable energy funds. First, certain types of state support— such as up-front grants and subsidized financing—appear to trigger the “double-dipping” provisions of the federal production tax credit (PTC), thereby reducing the value of the PTC. Second, receipt of a state incentive does not guarantee that a wind project will secure financing; renewable energy fund administrators must remain mindful of the need for a project to secure a long-term power purchase agreement as well. Despite some limitations, renewable energy funds can provide useful supplemental income to wind power projects, providing essential cash flow for project development.

Tax Incentives

Various types of tax incentives have been used at the state level in support of utility-scale wind projects. Whereas investment tax credits were common in the past, property and sales tax reductions and exemptions are now most common, with state production tax credits also gaining popularity. As with other types of incentives, tax incentives can reduce the cost of wind power. However, state tax incentives alone have seldom been sufficient to stimulate significant wind power development. Tax incentives can provide a useful supplemental revenue stream to wind plant owners. States contemplating tax incentives for wind, however, might keep several considerations in mind. First, although far from clear, state tax incentives might trigger the “double-dipping” provisions of the federal PTC, thereby reducing the value of the PTC to the wind project. Second, a wind developer or project owner may not have sufficient in-state tax liability to take full advantage of a state income tax incentive (note that this concern only applies to income tax credits, not to sales and property tax incentives). Allowing wind plant owners to carry forward the incentive into future tax years or to trade the incentive to other in-state taxable entities would address this issue. Finally, granting wind projects a property tax exemption could result in a lower level of local community support for wind power.

Resource Planning

In some parts of the United States, the cost of wind power is arguably competitive with the cost of fossil-fueled generation. In areas of the Pacific Northwest, the Midwest, and Texas, wind projects are selling their output at 3 cents/kWh or less. In such cases—particularly in regulated states—wind should be considered as a potential least-cost resource within an integrated resource planning (IRP) framework. Fairly treating wind power in utility resource planning involves fully considering the costs (e.g., cost of firming) and benefits (e.g., price stability and environmental benefits) of wind power within an integrated planning context, which typically occurs within public utilities commission proceedings. In one such IRP proceeding in Colorado, regulators deemed a wind plant to be the least-cost supply option, given the volatility of natural gas prices, and ordered the local utility to add wind power instead of gas-fired generation. As was the case in Colorado, however, such regulatory battles will typically be hard-fought and controversial because utilities are often inclined to resist wind power. Wind energy integration issues and forecasts of future natural gas prices are common areas of debate.

Environmental Credit Markets

If designed properly, state and regional policies that limit the emissions of pollutants such as NOx could present opportunities for wind power. In most permit trading programs, however, credits or permits are allocated only to polluting forms of generation, thereby denying the ability of nonpolluting forms to directly benefit. Several states, including Indiana, Maryland, Massachusetts, New Jersey, and New York have designed emissions trading programs to include limited set-asides for eligible renewable forms of generation. These programs can offer a modest additional revenue stream to wind projects.

Living off the grid

Atala — Tue, 06 Jul 2010 08:18:29 +0000

The shortage of power, the rapid consumption of non-renewable energy, the ever-increasing demand for power supply, the daily warnings about our environment are enough signs to tell us that it’s time we do something. So, what can we do? For starters, how about living off the grid? If I have startled you with that proposition, let me tell you that living off the grid not only helps the environment and helps save power; it also cuts down our electricity bill substantially. Now, that’s a tangible benefit apart from all the good you will do to the world. Trust me, you will feel good doing this.

Let us first study the advantages of living off the grid.

• Reduced dependability on exhausting resources: Who wants to depend on public utilities all the time? Living off the grid helps you rely only on your resources and not the ones supplied by governments or corporations. How often have you cursed when faced with a power outage in the midst of some important work or a party? Wouldn’t you like to take charge of such factors affecting you life? With alternate power solutions, you can.

• Freedom of usage of naturally available resources: How would you feel when you don’t have to pay for the power you use? Wouldn’t it be delightful to use as much power as you want without worrying about the electricity meter? You can make use of the abundant power available in the nature to light up your home and make your food. The solar power solutions and the wind power solutions are the answers to your power quest (well, literally!).

• Reduced power costs, helping save your money: How would you feel if the electricity bills stop coming in your letter box? The alternate power solutions give you a return on investment very soon, thus making the power supply to your home eventually free!

• Making way for a healthier environment: Don’t you bless the people who planted trees years ago not expecting them to miraculously grow? They planted those trees for the future generations. Make the future of your future generations secure by giving them a greener, healthier world. Cut down on the usage of non-renewable sources of energy. Try to use water minimally. There is not much drinking water left for the next generations.

If you are thinking it is not very feasible to live off the grid, look for alternate power solutions and you will be surprised to learn that they are not only cost-effective but also extremely feasible.

Municipal Utilities and Green Power

Atala — Sat, 03 Jul 2010 10:32:02 +0000

Randy Manion, Western Area Power Administration

As we continue in an era of fuel price volatility and risk in energy markets, the value of sound resource planning— hedging against a previously unforeseen range of possible market scenarios—is higher than ever. In addition, the importance of customer service and of delivering value to customers is higher than ever. Renewable energy—wind power—has valuable characteristics that can enable municipal utilities to address both of these concerns.

In the face of new and emerging market conditions, municipal utilities across the country find themselves at a crossroads. Load requirements are expected to continue increasing, while in many cases, existing supply contracts will end within the next few years. Further, customers throughout municipal utility service territories express consistently high levels of interest in renewable energy alternatives. In most cases, the preferred renewable technologies are solar and wind; given the cost advantage of wind, it is frequently the renewable of choice.

Municipal Utility Green Power Programs

Investor and publicly owned utilities around the country have begun offering renewable energy or green power options (generally referred to as green pricing programs) to their customers. The National Renewable Energy Laboratory (NREL) ranked utility green pricing programs based on a variety of criteria. They found that municipal utility green pricing programs were consistently among the most successful, regardless of the criteria used.

Los Angeles Department of Water and Power (LADWP): Green Power for a Green LA

The LADWP program is ranked in the top five in all categories. This program offers a low-cost, broad-based product to its customers. For a $3.00 monthly fee, residential customers can opt to receive 20% of their power requirements (about 100kWh per month) from renewable energy.

Austin Energy: Green Choice

Austin’s 61 wind turbines, located in Upton County, Texas, have a total capacity rating of 70 MW and will provide enough energy to meet the needs of 20,000 homes. Austin Energy has enrolled more than 6,500 participants, or approximately 2% of its customer base, in its Green Choice Program. Austin Energy customers who subscribe to Green Choice will see the normal fuel charge on their power bill replaced by a green power charge. Because of Austin Energy’s 10-year power supply contracts for wind and methane gas, the green power charge will remain fixed until 2011. Although the green power charge will never change for subscribers, other customers who choose not to participate in the Green Choice program will be subject to the fluctuations in fuel adjustment charges. Green Choice customers pay a premium of 1.1 cents per kWh.

Waverly Light and Power

In July 2002, NREL awarded its first Paul Rappaport Renewable Energy and Energy Efficiency Award to Waverly Light and Power for its contribution to the development of wind power in Iowa. Waverly began its wind program in 1991 when the city faced a power supply crisis. Since Waverly installed its first turbines in 1993, Iowa’s wind power capacity has grown to more than 300 MW. Iowa now ranks third in states with installed wind capacity, behind California and Texas.

Benefits to Municipal Utilities and Their Customers

More utilities are recognizing that wind power provides significant benefits to the utility and its customers. First and foremost, customers want renewables. Customer interest in renewables has been established repeatedly in customer surveys across the country. Second, wind power provides price stability benefits. Again, it has been amply demonstrated that price risk mitigation is important to a utility’s financial stability and is highly desired by risk-averse customers. Third, renewables provide significant local, regional and national environmental benefits. Finally, wind contributes substantially to local economic development, a benefit that will be of great importance to all municipalities.

Municipal Utilities’ Concerns with Using Wind Power

Municipal utilities have traditionally expressed three major concerns with incorporating wind power into their resource mix.

“Wind power is more expensive than available fossil fuel options.” Several factors have emerged to address this concern. First, the cost of wind power has dropped dramatically in recent years and, in some locations; wind is equal to the low-priced fossil fuel alternative on a levelized cost basis. Second, the lack of price volatility for wind generation reduces the costs of hedging fossil fuel price risk. Finally, in light of customer preferences, wind power can play a significant role in supplying value and satisfying customer needs.

“Because wind power is intermittent, the costs of transmission and ancillary services are increased.” This important issue is currently under intensive study. A variety of groups, most notably the Utility Wind Interest Group, are presently engaged in detailed studies assessing the impacts of wind generation on utility operations. Early results suggest that the costs of incorporating wind generation into utility resource portfolios are much less than traditionally believed. Although not definitive, the Bonneville Power Administration recently eliminated their generation scheduling imbalance penalty for wind generation (see the section on utility integration).

“Our utility is not familiar with wind technologies.” For municipal utilities that are concerned about their lack of extensive experience operating wind generation technologies, power purchase agreements are a viable financial and practical option. In addition, many municipal utilities are coming to the conclusion that wind power will be a significant component of their future resource portfolios and are making the decision to learn about this technology now.
