My six points outline:
1. Global energy mix
2. Generation cost, Electricity prices
3. Germany Case
4. UK Case
5. No climate basis for renewables cronyism
6. Conclusions
So despite decades of favoritism and subsidies to renewables by many governments especially in Europe, the share to total energy mix and electricity generation remains very small until this decade.
Just one major explanation: wind and solar are simply costly. Their energy density is low, their reliability and stability is low because they are intermittent. When the wind does not blow, when the Sun does not show up, electricity output is zero, even on days and hours that people want electricity.
When I went to south Sweden in 2003, I landed at Copenhagen airport in Denmark, then travelled by train to Malmo, then Lund. Before the plane landed, I saw many windmills on the sea in Denmark, the offshore windmills. They looked cute.
Europe being a very modern continent, and Germany and UK
being highly industrialized countries, and
yet there are stories and reports
of “EU risks blackout”, a “dark continent”, and “impossible green dream”.
In developed Asia like Hong Kong (electricity, 71% from
coal, 29% from natural gas, zero from renewables; Singapore 78% from natural
gas and 18% from oil, very small from renewables (as of 2011, from ADB’’s Key
Indicators 2014) ); S. Korea and Japan,
the words “blackout” or brownout” or “dark continent” are never heard. They
have huge, stable and reliable energy supply, at cheap prices, their energy policies have not been
hijacked by green socialism yet.
Below,
IV. UK Case
The reason why if there are wind farms, there are no houses,
no fishing or farming village, no beach resorts, almost no other economic
activity. Those wind towers can fall down, wind turbines and blades can get burned and fall down. The economic trade
off of having more wind farms is huge. Plus huge amount of mining and production
of iron and steel, cement and other mineral products.
Climate change (CC) is true. It happened in the past,
happening now, and will happen in the
future. Global warming (GW) is true, it happened in the past (last century,
Medieval warm period, Roman warm period,…), and will happen again in the future. Global cooling is also true, happened in the past, happening now.
Because CC is natural (nature-made, not made), it is
cyclical (warming-cooling-warming-cooling), and has precedents (not
“unprecedented”). Skeptics (like me) do not deny CC or GW because these are
true. What we deny is that CC and GW is “man-made” or anthropogenic. CC is
caused by nature (the Sun, galactic cosmic rays, water vapor, volcanoes, ocean
oscillation, carbon cycle, hydrologic cycle,…).
Below, warming-cooling cycle coinciding with CO2
concentration. One study says temperature leads CO2, other studies say it’s the
reverse. Common denominator, there are precedents of warm period, lasting for
decades & centuries.
3. Renewables are fine, provided there should be NO
subsidies. People can put up solar panels in the roof of their houses and buildings, fine. People can put up wind towers in their farms and private property, fine. They
are using their own money, taking their own risks and benefits.
4. It is
different when people put up wind farms or solar farms in huge areas including public
forest lands, because they want to get paid huge money (via RPS and FIT) at the
expense of consumers. FIT is the guaranteed minimum for renewables. While coal,
nat gas, big hydro geothermal can be
priced down to P1/kWh or even less during
non-peak hours, renewables are guaranteed to be paid FIT rates.
5. Cases of Germany and UK show that government
intervention and cronyism in energy policy is wrong and counter-productive. Governments should get
out of electricity pricing, stop forcing grid operators and electricity
distributors to buy first from renewables even if their rates are expensive.
6. There is zero climate basis for
renewables cronyism. There is
zero justification for governments to
intervene heavily in energy production mix and electricity pricing.
