Costs

The alarming conclusion of a 232 page report to the Secretary of State for Business Innovation and Skills is that compared with China, India, Japan, Russia, Turkey, US, Denmark, France, Germany and Italy, electricity prices in the UK are forecast to be vastly more expensive for industries such as Aluminium, Iron and Steel manufacturing. This is the result of the UK’s policies to subsidise renewable energy and tax fossil fuel use. Tata Steel’s European Chief Executive, Dr Kohler, said the company faced higher energy costs in the UK “due to Government levies and fees” than competitors overseas. This throws into question the future of the Number 4 Blast Furnace at Port Talbot, part of the state of the art £240 million investment in plant that Tata has committed to in South Wales.

The price we pay ….

Over the past decade, wholesale electricity costs have risen by 140 per cent, while gas prices have increased by 240 per cent, according to Ofgem.

Energy firms blame rises on higher wholesale prices, the increased cost of delivering gas and electricity to our homes and the Government’s expensive green taxes.

The situation is that:

Suppliers are meant to bill us for environmental projects.

These include:

Finally there are residential energy-efficiency programmes

The latest Government breakdown shows that in 2012:

Energy Cost Estimates 2012  

Colin Gibson, former Power Network Director at the National Grid Group, has produced some of the most comprehensive estimates including add-on costs of all energy:

Trading in Weather derivatives

“Energy companies are the best bet for future growth as well as current revenues. There have been some big transactions with companies that generate hydropower, which requires consistent snow and rain. Products based on sunshine for the solar industry are now available. And some firms are offering contracts to limit the exposure of wind farms to either a lack of puff or gusts that are too strong for turbines. This is helping energy firms to raise cash to invest in pricey wind projects by guaranteeing long-term returns from unpredictable blasts of air. If so, an ill wind might now blow some good.”

The Economist

In October 2013, the UK govt. agreed a deal with EDF to build a nuclear plant at Hinckley Point. When it comes on line (in about 10 years) power will be purchased at £92.50/MWh

Can you make wind turbines without using fossil fuels ?

… asks Rob Wilson in Theenergycollective.

The current feasibility of 100% renewable energy is easily tested by asking a simple question. Can you build a wind turbine without fossil fuels? If the machines that will deliver 100% renewable energy cannot be made without fossil fuels, then quite obviously we cannot get 100% renewable energy.


This is what a typical wind turbine looks like:

What is it made of? Lots of steel, concrete and advanced plastic. Material requirements of a modern wind turbine have been reviewed by the United States Geological Survey. On average 1 MW of wind capacity requires 103 tonnes of stainless steel, 402 tonnes of concrete, 6.8 tonnes of fibreglass, 3 tonnes of copper and 20 tonnes of cast iron. The elegant blades are made of fibreglass, the skyscraper sized tower of steel, and the base of concrete.

Forgetting the concrete, fibreglass and copper, the ore for iron has to be quarried, transported and processed. Try running the freighter & road transporter on wind or solar power !!! (Images from ‘theenergycollective’)

Cost Update for 2014

2014 - More about Wind power costs

Ed Hoskins has done an analysis of cost ratios, which used to be available as a blog on Wordpress but which has recently disappeared.

However, in summary, the figures show that the three major nations of the Western world have spent about $0.5trillion to create Renewable Energy electrical generation capacity, nominally amounting to 5.8% of their total generation. This capacity could be reproduced using conventional natural gas fired electrical generation for $31 billion or 1/16 of the costs expended.

Had conventional Gas Fired technology had been used, the full 31 GW capacity would have provided non-intermittent electricity production and wholly dispatchable power could be generated as and when needed.
