Wind energy Energy return on investment
IntroductionWind energy is one of the fastest growing energy systems in the world. In Europe and the United States, wind-powered generating capacity increased by 18 percent and 27 percent, respectively, in 2005 alone. While the rate of increase is impressive, wind still accounts for less than one percent of the world's electricity generation. The surge in wind energy is due to a combination of factors, including reduction in the cost of wind turbines, volatile prices for conventional forms of energy, the demand for non-carbon forms of energy to mitigate the effects of climate change, and generous government subsidies such as feed-in tariffs in Europe and the production tax credit in the United States. Figure 1: Energy outputs and energy costs of a power generation facility. One technique for evaluating energy systems is net energy analysis, which seeks to compare the amount of energy delivered to society by a technology to the total energy required to find, extract, process, deliver, and otherwise upgrade that energy to a socially useful form. Energy return on investment (EROI) is the ratio of energy delivered to energy costs. In the case of electricity generation, the EROI entails the comparison of the electricity generated to the amount of primary energy used in the manufacture, transport, construction, operation, decommissioning, and other stages of the facility's life cycle (Figure 1). Comparing cumulative energy requirements with the amount of electricity the technology produces over its lifetime yields a simple ratio for energy return on investment (EROI): EROI = (cumulative electricity generated) / (cumulative primary energy required) This article reviews 112 wind turbines from 41 different analyses, ranging in publication date from 1977 to 2006. This survey shows average EROI for all studies (operational and conceptual) of 24. 6 (n=109; std. dev=22. 3). motorcyclist paige parker rogers The average EROI for just the operational studies is 18. 1 (n=158; std. dev=13. 7). This places wind energy in a favorable position relative to conventional power generation technologies in terms of EROI. Methodological Issues System Boundary The choice about system boundaries is perhaps the most important decision made in most in net energy analyses. One of the most critical differences among the diverse studies is the number of stages in the life cycle of an energy system that are assessed and compared against the cumulative lifetime energy output of the system. These stages include the manufacture of components, transportation of components to the construction site, the construction of the facility itself, operation and maintenance over the lifetime of the facility, overhead, possible grid connection costs, and decommissioning. Energy systems have external costs as well, most notably environmental and human health costs, although these are difficult to assess in monetary and energy terms. No study as yet attempted to assess the environmental costs of wind energy in energy terms. Methodology Three types of net energy analysis techniques are used to calculate the net energy derived from wind power: process analysis, input-output analysis, and a hybrid analysis. The assumptions, strengths, and weaknesses of these approaches are discussed here. Operating Characteristics Many analyses must make important assumptions regarding the operating characteristics of wind turbines. These include power rating, assumed lifetime, and capacity factors. Changes in the assumptions made about these factors, or deviations in actual operating conditions from assumed conditions can have a significant impact on results. Conceptual versus Empirical Studies Some studies use the theoretical or ideal operating characteristics of a wind turbine that are derived from simulated or assumed costs and operating conditions, e. g. , a wind turbine of a given power rating, costing a certain dollar amount, in a location with an assumed wind power density, with an assumed capacity factor, and so on. Of course, actual operating conditions always deviate from assumed conditions. Empirical analyses rely on actual costs, operating conditions, and energy outputs, and thus provide a better metric of an energy system's contribution to a nation's energy supply. This article focuses primarily on empirical studies based on actual operational data. Results Table 1: The EROI for wind turbines. Table 1 provides the detailed technical results of the wind studies. The data include the year and location of the study, key technical assumptions such as load factor, power rating and lifetime, system boundaries, the type of net energy method used, and the EROI. The table also distinguishes between studies based on actual performance of a wind system and conceptual studies based on theory or simulations. The average EROI for all studies (operational and conceptual) is 24. 6 (n=109; std. dev=22. 3). The average EROI for just the operational studies is 18. 1 (n=158; std. dev=13. 7). Discussion EROI and Turbine Size One of the striking features of the studies is that the EROI generally increases with the power rating of the turbine (Figure 2). This is probably due to several reasons: first, smaller wind turbines represent older, less efficient technologies. The new turbines in the megawatt (MW) range embody many important technical advances that improve the overall effectiveness of energy conversion. Although larger turbines require greater initial energy investments in materials, the increase in power output more than compensates for this. Figure 2: EROI vs. wind turbine power rating. Second, larger turbines have a greater rotor diameter, which determines its swept area, which probably is the single most important determinant of a turbine's potential to generate power. A turbine with respectable power rating but a rotor diameter so small that it can't capture that power until the wind speed reaches very high velocities will not produce a reasonable annual energy output. Again, larger rotors require greater initial energy investments in materials, but the increase in power output more than compensates for this. These conclusions are consistent with the finding that commercial wind farms have moved towards larger turbines that are less expensive with regard to installation, operation, and maintenance. The greater cost efficiency of larger turbines is largely attributed to economies of scale and learning by doing. Accordingly, under a similar assumption, larger turbines have a greater efficiency in respect to EROI. Another reason that larger turbines have a larger EROI is the well-known "cube rule" of wind power, i. e. Silver Mania, What Is A Dollar? , that the power available from the wind varies as the cube of the wind speed. Thus, if the wind speed doubles, the power of the wind increases 8 times. New turbines are taller than earlier technologies, and thus extract energy from the higher winds that exist at greater heights. Surface roughness - roughness determined mainly by the height and type of vegetation and buildings - reduces wind velocity near the surface. Over flat, open terrain in particular, the wind speed increases relatively fast with height. Influence of Production Country EROI is affected by the location of a turbine's manufacture and installation. An anaysis of the EROI of conceptual wind turbines produced and operated in Germany and Brazil shows a range of 5 to 40:1. Such a large range in wind turbine EROIs is a function of differences in the energy used for transportation of manufactured turbines between countries, the countries' economic and energy structure, and recycling policies. Production and operation of an E-40 turbine, standing 44 meters high in a coastal region in Germany requires approximately 1. 39 times more energy, or 3. 9 times more input energy per kWh of output energy, than the production and operation of the same turbine in Brazil. This assumes that Brazil's conversion efficiency in the electricity generation system being above 90% is the main reason for the difference in energy inputs, showing that the production scenario has a greater influence upon the magnitude of input energy than site conditions or transportation. Comparison with other power systemsFigure 3: EROI of various electric power generators. The EROI for wind turbines compares favorably with other power generation systems (Figure 3). Baseload coal-fired power generation has an EROI between 5 and 10:1. Nuclear power is probably no greater than 5:1, although there is considerable debate regarding how to calculate its EROI. The EROI for hydropower probably exceed 10, but in most places in the world the most favorable sites have been developed. Challenges facing wind energy Does the high EROI for wind power presented here guarantee that wind will assume a major role in the world's power generation system There are a number of issues surrounding wind energy that require resolution before that happens. The dramatic cost reductions in the manufacture of new wind turbines that characterized the past two decades may be slowing. Part of the slowing may be due to transient factors such as short-term increases in raw material prices; unfavorable exchange rates; insufficient global and domestic manufacturing capability (exacerbated by short-term uncertainty in government subsidy policies); and exercise of market power by the consolidating manufacturing industry. It also is possible that the industry is experiencing diminishing returns to cost reductions via learning-by-doing. The uncontrolled, intermittent nature of wind reduces its value relative to operator-controlled resources such as coal, gas, or nuclear generation. Intermittency impacts include the seasonal and diurnal match or mis-match to regional energy demands; the contribution of wind energy to capacity reserves for meeting regional reliability requirements; and the lost value to wind plant owners in surplus generation that occurs when wind power saturates the flexible dispatch portion of grid operations. Wind energy also affects the overall reliability of the electric power system, which is represented in part by the system reserve margin - that is, a margin of total installed capacity above projected peak load. The capacity credit of an isolated wind plant is generally equal to its capacity factor during the system's peak load period, which normally is less than an operator-controlled source. As more wind capacity is added to a system within a finite geographic area, it becomes increasingly likely that an -outage- at any given facility will be temporally correlated with an -outage- at a nearby (or even not-so nearby) plant. This tends to reduce the average capacity credit for a wind plant as more such facilities are added in a region. Much of the wind resource base is located in remote locations, so there are costs of getting the wind from the local point-of-generation to a potentially distant load center. This cost is distinct from the cost of simply interconnecting the site to the nearest transmission line. Even at the relatively low current levels of wind penetration on regional grids, long-distance transmission has already proven to be a significant issue for new wind development in some regions. For example, wind plants in Texas have had to curtail output during hours when regional trunk lines are at physical capacity, and Minnesota and California are currently examining ways to alleviate transmission congestion as more development is proposed in their best wind resource areas. These costs are not reflected in most EROI analyses. The remoteness of the wind resource base also generates the cost of developing land with difficult terrain or that which is increasingly removed from development infrastructure (such as major roads, rivers, or rails capable of transporting the bulky and heavy construction equipment). To the extent that local roads or bridges cannot accommodate blade shipments in excess of 50 meters (over 160 feet) length or nacelle shipments of 50 tons or more, they must be upgraded, rebuilt, or (retroactively) repaired as a part of the plant development process. Little is known about the extent of these costs. At about 6 or 7 megawatts per square kilometer of net power potential, wind plants are necessarily spread-out over a significant land area. Thus, wind plants must compete with alternative uses of these land resources. In some cases such as agricultural land, multiple simultaneous use is possible. In other cases the competition is stiff. The value of some lands for other types of development (such as urban or housing development) has limited and will limit wind power location options. This is especially true when the land is a signficant source of aesthetic and/or recreational value. Another issue confronting wind energy is the uncertainty of future government subsidies. Much of the recent growth on wind energy around the world has been made possible by government subsidies such as the wind energy Production Tax Credit (PTC) in the United States and feed-in tariffs and renewable portfolio standards in Europe. While there is strong support in many nations for such support, shifting political winds can create uncertainty for manufacturers and utilities. For example, the wind PTC in the United States was scheduled to expire on December 31, 2005, but was extended to December 31, 2007 by a federal energy bill. The PTC provides a 1. 9 cent-per-kilowatt-hour (kWh) tax credit for electricity generated with wind turbines over the first ten years of a project's operations, and is a critical factor in financing new wind farms. The inconsistent nature of this tax credit has been a significant challenge for the wind industry, creating uncertainty for long-term planning and preventing faster market development. There is also concern about the impacts of wind energy on birds and bats. Early research on the avian impacts of wind energy at places such as Altamont Pass, California, suggested that the wind turbines killed significant numbers of raptors and other birds. In 2004, a large number of bats were killed by a wind farm in West Virginia. The issues surrounding avian and bat mortality have just begun to be studied, so the full potential risk is largely unknown.
