The Problem

The problem should be of foremost concern to advocates of Renewable Energy. Wind power forms the primary basis of their hopes, yet wind power receives poor marks when graded for efficiency and economy. Wind power cannot compete with other sources of power without the support of incentives and subsidies granted through public policy, but such policy is vulnerable to shifts in the political wind. Hence, wind power investments entail a degree of political risk, especially if public policy promotes wind power over more efficient, and less costly, sources of power. Such policy leads to higher prices for electricity and many consumers, particularly industrial consumers, chafe against this. Those who object to the inflated electricity costs are not without influence. Thus, manufacturers threaten to emigrate from Germany over such issues, and the Green Party there has suffered disastrous defeat in the latest pollings ( See Bloomberg Aug 1, 2024, “Four in Ten German Manufacturers Eye Move Abroad on Energy Costs”).

Other clouds are gathering on the horizon of the wind power industry. One such cloud is the snow-balling issue of decommissioning. This involves the costly dismantling of worn-out wind turbines and disposal of the giant blades. Decommissioning levies a huge tax on wind farm returns, these being skimpy to begin with and shrinking considerably through the cost of  decommissioning. The unhappy owners of a wind farm, some twenty years after getting in, find that getting out brings one more lesson in the economics of wind power.

The disposal of these turbine blades near Sweetwater, Texas, is the subject of a law suit filed by GE Renewables. A jack-up barge outfitted with a boom dismantles a wind turbine situated offshore, Denmark.

There are clouds looming over offshore wind power, which has been vigorously promoted as the future of wind power. In fact, offshore wind farms are projected as enormously costly, at over twice the cost of onshore wind power projects, and therefore require much higher subsidies than onshore wind farms. Developers of such projects have applied, but authorities are unwilling to grant the extravagant subsidies they demand. Without the benefit of adequate subsidies, investors shy away from offshore wind power projects which then languish in the planning stage, or even are wholly abandoned. Such cloudy-day lessons are not lost on those with funds to invest, of whom a growing portion see reasons to stay out of wind power. Thus, many wind turbine projects have difficulty getting out of the planning stage, as the needed funds are slow in coming. We may see the day when the installation of new turbines is balanced by the decommissioning of an equal number of worn-out turbines, unless a solution appears that remedies the poor economics of wind power.

More lessons in wind power. Such fires are usually due to overheating of the reduction gears. The collapsed turbine suffered structural failure, which has various causes.
