“…By using a large number of smaller plants, the potential danger of over building or commissioning less cost effective large plants could be avoided. Small plants can be added quickly as they are needed and even disassembled and moved if loads decline; the economics of the larger plants depend heavily on long-term forecasts (Johannson et al, 1993;Kelly and Weinberg, 1994).…”

“…If the small generators are scattered throughout the region, a number of other benefits emerges: heavy pollution of a region (congestion) is avoided; employment (less rural exodus) and community participation (awareness) is also increased in distributed power generation. Ideally, each region should become self-sufficient in electricity generation; if the demand exceeds its supply, the utility in that region imports electricity from the neighboring utilities, and similarly, the excess capacity is also sold to the neighboring utilities (Johannson et al, 1993;Kelly and Weinberg, 1994). …”

“…To ensure system reliability, 8 the system operator has to reckon with the non-availability of wind-solar power during parts of the day and possibly during hours of maximum demand. As a consequence, for each additional MW of wind-solar capacity that is installed, only a small part can be considered to be available capacity from a system operating point-of-view.…”

In this study we explore for the USA and OECD Europe (OECD Europe includes the countries that participate in the Organisation of Economic Cooperation and Development, among which Western Europe, USA and Japan) dynamic changes in electricity production, cost and CO 2 emissions when intermittent electricity sources are used with increasing penetration levels. The methodology developed can be applied for both solar photovoltaic (PV) and wind energy. Here the focus of the results is on penetration of wind electricity in the electricity system as simulated in a long-term model experiment in which the electricity demand is kept constant over time. All important parameter are included in a sensitivity analysis. With increasing penetration levels the cost reduction of wind electricity caused by upscaling and technological learning is counteracted by the cost increase due to (1) the need for additional back-up capacity, (2) the need to generate wind electricity at less favourable sites, and (3) discarded wind electricity because of supply-demand mismatch. This occurs after about 20% wind electricity production as percentage of current electricity production. At this level about 500 (OECD Europe) and 750 (USA) TWh yr À1 wind electricity is absorbed in the system with the electricity demand of the year 2000. Wind electricity is found to be discarded when the production is about 55 (USA) to 10 times (OECD Europe) the present electricity produced from wind power. Beyond 30% of present electricity production, cost increases most significantly because of discarded wind electricity, excluding storage. In both regions the use of wind electricity would mainly avoid use of natural gas. The CO 2 emissions abatement costs range from 14 (OECD Europe) to 33 (USA) $ per ton CO 2 differ in both regions due to a faster wind electricity cost increase in OECD Europe. r

“…A substantial potential is believed to exist in the world for renewables; for biomass (Johansson, et al, 1993), 4,900 Mtoe/a; for hydropower (World Energy Council, 1995), 780 Mtoe/a (electric); and for windpower (Sorensen, 1995), 4540 Mtoe/a (electric). Roughly half of these energy resources are in developing countries.…”

The world population is rising rapidly, notably in the developing countries. Historical trends suggest that increased annual energy use per capita is a good surrogate for the standard of living factors which promote a decrease in population growth rate. If these trends continue, the stabilization of the worlds population will require the increased use of all sources of energy as cheap oil and gas are depleted. The improved efficiency of energy use and renewable energy sources will be essential to stabilizing population, while providing a decent standard all over the world.
