Wind power can create a situation where "power is too cheap to meter" Photo: Jukka Seppälä/Creator's Fingerprints
In 1950ies and 1960ies they told us that nuclear power would be so cheap that by now it should be too cheap to meter.

This scenario turned out to be ultra-optimistic and the real costs of nuclear power are very difficult to count but are far from free power. In fact it seems that if all costs are combined (planning, construction, running, back up systems, accidents, health consequences, nuclear waste, decomissioning and clear weapons proliferation) then nuclear power is the most expensive way of power generating.

But wait a minute - could there be energy sources that generate power almost without costs?
In fact, none. But if you think about old hydro power, wind or solar PV, you have no fuel costs. Only the payback of investement of constructing, transformers and the grid. And maintenance costs. Well, thats a lot of money. But when you have paid the investment, the price of energy remains low. For example the low price of hydro power is pulling down prices on Nordic power market. When the new wind parks will be starting their power generating, the price will be going further downwards.
And last summer - yes it's true - the power price in Germany was almost zero during windy, sunny days. Those moments were short, but they did exist. Wind power combined with solar PV capacity was creating a situation "too cheap to meter". Still the consumers payed full price for their power but this event shows the direction for the future. Many studies have shown out that renewable energy can offer power with lower prices than our coal-nuclear power plants do today.

So we have a clean and sustainable and economical way to go. Let's take the renewables seriously!
