We are learning quickly, and costs are plummeting through the sheer volume of construction: 40,000 wind
turbines
over the past decade in Europe alone.
Spending on transfer payments and/or nonmilitary purchases – which can become entrenched or be procured more cheaply from abroad (for example, solar panels and wind turbines, respectively, in America’s 2009 fiscal stimulus) – is also likely to yield only a small multiplier.
Chinese companies already play a major role in all the major technologies needed to power the green economy, including photovoltaic panels, wind turbines, batteries, and the sophisticated systems required to manage the interaction of intermittent electricity supply and time-varying demand.
But the world’s poorest don’t want solar panels or wind turbines: they have much more immediate needs, not the least of which is for modern energy – which mostly means more access to fossil fuels.
We see scary pictures of dry riverbeds (the result of global warming), along with plenty of pretty solutions like wind
turbines
and solar panels.
Even with their large and noisy turbines, offshore wind farms produce, at their peak, as little as nine megawatts per square kilometer.
To match a one-gigawatt coal-fired plant requires several hundred
turbines.
A signatory of the Business Backs Low Carbon letter, Mars is working to eliminate its greenhouse-gas emissions entirely by 2040, through greater efficiency and investment in renewable energy projects like wind
turbines.
During the 1830’s, the first water
turbines
marked the beginning of the end of the waterwheel era.
Most of the world’s electricity is generated by steam
turbines
in fossil-fuel-burning and nuclear power plants, and, except for much larger capacities and higher efficiencies, Parsons would recognize in them every key feature of his invention, now more than 120 years old.
And intercontinental flights would be an even greater trial without the gas
turbines
invented in the 1930’s by Frank Whittle (who thought about turbofans, now the dominant commercial design, even before he built the first turbojet) and Joachim Pabst von Ohain.
There has been little real innovation ever since these prime movers were first commercialized more than a century ago (water turbines, steam turbines, internal combustion engines) or more than 50 years ago (gas turbines).
Even today, for example, there are few indications that steam
turbines
will not continue to generate the bulk of our electricity in the decades ahead, or that gas
turbines
will be replaced anytime soon.
For example, if 20% of the world’s electricity were to be generated by wind turbines, then, considering their inherently low load factor of about 25% (compared to 75% for thermal stations using steam turbines), we would need to install new capacity of some 1.25 TW in these machines.
Even with large 3-MW turbines, this would require more than 400,000 new tall towers and giant triple blades.
Land allocated to wind power is not lost to agricultural production, because crops can be grown and animals grazed between the
turbines.
Examples include high-speed trains (41% of global revenue), wind
turbines
(20%), and communications equipment (18%).
The CMS signatory countries are set to consider adopting resolutions to mitigate a range of threats to migratory wildlife, including the establishment of stricter guidelines on the location of wind turbines, as well as boosting efforts to restrict the proliferation of marine debris.
One well-tested method for storing energy is to use excess capacity to pump water into reservoirs, so that it can be used later to power
turbines
when demand is high.
South Africa has some of the world’s largest deposits of chrome and manganese, minerals that are essential for the manufacture of electric vehicles, wind turbines, and other components of the so-called Fourth Industrial Revolution.
Solar cells and wind
turbines
require less than 1% of the area of forests to reduce CO2, they become increasingly efficient, and they can often be placed on non-productive land (such as wind
turbines
at sea and solar panels in deserts).
And while renewables’ opponents are legion, they are motivated more by interest in preserving the status quo of fossil fuels and nuclear energy than by worries that wind
turbines
or solar farms will blot the landscape.
Countries can build their way to energy security by investing in the industrial capacity needed to produce wind turbines, solar cells, and other sources of renewable energy at scale.
This is what officials ignore when, as Dutch Prime Minister Mark Rutte put it, “wind
turbines
are powered by subsidies.”
With 131
turbines
and a daily capacity of more than 300 MW, Tarfaya will help reduce Morocco’s carbon dioxide emissions by 900,000 tons annually, and cut the country’s annual oil import bill by more than $190 million.
Millions of small machines – photovoltaic cells, wind turbines, batteries, and smart appliances – are driving today’s energy transformation.
A good illustration is Denmark, which early on provided huge subsidies for wind power, building thousands of inefficient
turbines
around the country from the 1980’s onwards.
Not surprisingly, the leading Danish wind producer is today urging strong action on climate change that would imply even more sales of wind
turbines.
And investors in General Electric, including BlackRock, lost a whopping $193 billion in the three years leading up to 2018, because the company misjudged the pace of the shift to green energy and the collapse in demand for gas
turbines
and thermal power stations.
Finally, governments must support new technologies with initial deployment subsidies of the sort that have helped to reduce rapidly the costs of solar photovoltaic technology, wind turbines, and batteries.
