The energy debate continues to go in circles. Usually its starts with the renewable sector heavyweights: wind and solar. The free and usually reliable inputs of wind and sun are very attractive. The technology is improving and, in the case of solar energy, the transmission mechanism is close at hand.

One company in the US has actually started a rental program for solar heating. I like this idea because capital cost is a problem for many people. Energy as a service is a good business model.

Solar is a great option because you can localise it. Hopefully the technology will continue t to improve.

Wind has its drawbacks due to the requirements of location and serious land mass. But again it suits some places better than others. But how about small wind turbines on every roof?

Little and often i say. Every little bit counts.

Biomass is the latest technology on the block, a small step up from chucking wood in the burner which is very popular and cheap in New Zealand. We can grow a lot of wood down here. The biomass and biofuel solution reveal a problem in our approach.

It doesn’t have to be one or the other. It can be both/and. It’s clear now there is no one solution that is way better than another. Let the market continue to work it out. And this brings me to the main point which is that we must have a properly priced energy market.

This is going to require a major change. I have long banged on about pricing in environmental costs at source and whilst Trucost is doing great work in that area there is a long way to go.

So how could this work? Well here are a few examples:

Carbon

Let’s say we have established a price for “carbon”,this being a proxy for externalities caused in the combustion of fossil fuels. The most efficient way to alert the market to this cost is to price it in at source ie where the fossil fuel is sold wholesale. This would be the global oil, gas or coal exchanges.

In my paper, Climate Control, i argued for the establishment of a World Energy Agency, where all fossil fuels were sold through. Simply add on the price of carbon and leave it at that. As a one point global process it would be very simple and then that price information would flow out across the world. End of story.

But there are two issues here:

One is that we are trying to stop carbon quantities breaching certain levels. The price elasticity of fossil fuel consumption may hinder this somewhat as consumers of oil products are slow to change demand in response to price.

The second issue is interesting. What happens to that money? Who does it belong to? As a charge being levied by the WEA it has no soveriegn recipient. So i propose this “charge” goes into a Global Environmental Contingency Fund (GECF). I want to make clear this is not a tax, it is a cost. It is therefore directly related to an expense which is in this case the use or environmental services.

Let’s stop using the word tax. It’s incorrect and draws attention from the fact that we are simply paying for a service we are using.

So how could the GECF work? I have to give that some more thought but the rough idea is that it would hold those funds in bonds (sovereign) or could lend them out at low interest to fund projects that have a positive environmental benefit. This is the tricky bit. But let’s sit with the first piece. The money comes in and sits in bonds. That’s it. So it’s not being spent on projects of a dubious outcome. As the title implies its a Contingency Fund. We don’t know for sure what will happen in the future. The money can be repaid if required by discounting the price of fossil fuels if it turns out that the cost has turned out to be lower.

It’s a hard one to get right on  a global level but worth a look.

Agriculture

In New Zealand we have trouble with dairy farming, a highly profitable business which has seen huge swathes of land converted from other activities to supporting cows. The externalities of this business are numerous but center around water pollution through fertilizer run off into streams and down into the water table as well as cows crapping all over the place..oh yes and the methane burps.

Here it would be simpler. A charge would be applied per head of cattle and immediately be applied to cleaning up that pollution at source. Why should the taxpayer pick up this tab. Its a cost for the consumer to bear and if the consumer doesn’t like the slightly higher price then the producer will quickly alter his habits.

The moral of this  story is simple: We need to know the true cost of our global economic activity. Then as consumers we can respond appropriately.

Trying to say which energy source is better than another is simply guesswork.
