Are Green Energy Policies Effective - or are they all Failures

Whilst this article [Link Below] mainly blames the politicians, the main issue it neglects to cover with regard to cleaner energy methods [Wind, Sun, Tides and Bio-Digesters] is that of the distortion that misaligned subsidies have.

The initial subsidy for Solar Photo-Voltaic [Solar PV] was so over-generous that a massive 'industry' of direct-selling organisations sprang up almost over-night. These panels soaked up so much subsidy that the scheme has been massively cut back - so who set the original subsidy at 44p per kWh? Way, way over the current retail price of electricity - and not into the best technology either.

Now efficiency of 'renewables' [cleaner technologies is a better description; and certainly not wood pellet burning technologies] is often slated as the reason whey they are not effective or efficient.

• Now the photo below shows steam [yes STEAM] rising from the cooling towers [yes COOLING TOWERS - not Chimneys] - probably Drax with a total of 8 Cooling Towers, ARE DESIGNED TO WASTE AROUND 60% of the energy released from burning Coal or even wood pellets - its the engineering answer to "efficient energy production" [...of a large scale remote power station].



Power Station Cooling Towers Wasting 60% Heat

• However the electricity generated under centralised power plants like this is rarely above 22% at the plug in your house. Some say as low as 11%.

This in-efficiency [in centralised power systems] could have been solved by utilising lots of smaller power plants, built close to towns and cities which would not necessitate Cooling Towers, as waste heat can be distributed to houses and industry - just like in Denmark. Its called de-centralised power or even embedded power where tiny street corner electricity and heat for distribution are generated. So these remote [centralised] power stations are part of our problem.

Embedded Power Islington

Tidal projects also suffer from 'pilot project issues' and unnecessarily high subsidies - so the technology is fine, the "power" is clean and there is zero fuel cost - so lets look into differing cost models and subsidy strategies - this is the problem - how to assist innovation.

Turn Down Markets

Innovative, carbon free ‘turn-down’ demand response sector delivering for consumers

23 Mar 2017

Capacity Market results announced today mean dozens of industrial and local businesses will help keep the lights on at peak demand next winter and cut carbon through innovation in the demand response sector, the Association for Decentralised Energy said.

Reducing Energy Loads

Approximately 312 MW of carbon free turn-down demand response has been secured as part of the Transitional Arrangements auction, which is aimed at preparing and supporting this innovative sector for the main Capacity Market auction.

The auction, which cleared at £45 per kW on Wednesday, means businesses across the UK will earn just over £14m in revenue, helping them to manage their energy costs and boost their competitiveness simply by turning down or shifting non-critical processes. Examples of demand turn down include temporarily switching off unnecessary lighting, pumps and motors, while demand shifting is the practice of moving a business process to earlier or later in the day.

There is nearly 10GW of untapped business led demand response, including highly efficient combined heat and power, ready to support the UK’s energy security. To achieve this potential however, user led demand response must be able to access all markets, from the Capacity Market and Balancing Mechanism to the Wholesale Market and ancillary services market, on an equal footing with traditional generation.

ADE Director Dr Tim Rotheray said:

"Today’s results are returning value to energy users for helping keep the lights on, while also cutting emissions through zero carbon demand response. Instead of paying power stations to increase supply, businesses will be managing demand in innovative ways while meeting all their energy needs leading to a more efficient, more affordable and lower carbon system.

"This auction is designed to help lower costs and improve uptake of demand response so that this tool will play a key part of the future energy sector. The Transitional Arrangements are vital in supporting this innovative sector to grow, deliver Britain’s security of supply needs and ultimately help drive a more competitive demand response market."

Auction results
A total of 373 MW entered the Auction, of which 83.69% received Capacity Agreements for delivery in 2017/18.
