Green energy: why wind power will never be the answer

Wind farms only work with permanent public subsidy. Subsidy comes in various guises. The most obvious is contractual where the operator receives a guaranteed rate for electricity generated or a guaranteed top-up on what he sells his electricity for.

Such subsidy is inherently neither problematic nor exceptional. Nuclear power is also heavily subsidised.

Wind power is problematic because of its nature. Because they depend on wind, wind farms generate electricity that is unpredictable, intermittent and unreliable. This is unlike nuclear power stations which produce a constant stream of electricity (baseload energy) or gas plants, whose output can be varied on demand (dispatchable energy).
Wind’s intermittency would matter less if electricity could be stored at scale. But batteries only store comparatively small amounts, and there is no prospect of affordable batteries for grid-scale storage in the foreseeable future.

Electricity can be stored as potential hydro-electric power by pumping water uphill into reservoirs for release when required, like the Cruachan dam which operates as an adjunct to the Hunterston nuclear power station. However, Scotland lacks enough suitable topography, as well as the political will and money, to turn glens into hydro-electric power reservoirs for wind farms.

With storage not an option, the only way to control wind’s vagaries is to accommodate it within the wider electricity system, using primarily gas and nuclear generators to provide dispatchable and baseload power when wind can’t.

Balancing it in the wider electricity system constitutes a further subsidy, for it requires upgrades and extensions to the grid as well as keeping gas plants running on stand-by (“back-up”). But using the grid and other generators to make up for wind’s shortfalls becomes more challenging and expensive, the more wind generation enters the energy mix.

Increasingly, the grid is unable to take electricity from wind farms during windy periods. Wind farms are then “constrained off”, the energy effectively wasted and their operators compensated – last year to the tune of £125 million.

While the precise causes of the August 9 blackouts in England, in which Hornsea offshore wind farm is implicated, remain unclear, they testify to the increasing fragility of a national electricity system struggling to meet the challenges of increasing renewable generation.

Like other European countries, the UK has reformed its subsidy regime in response to galloping wind farm development, exploding subsidy costs and ever-rising consumer bills. Abolishing the Renewables Obligation in April 2016 sounded the death knell for new onshore wind farms.

The focus shifted to offshore wind farms, and the new Contracts for Difference scheme for their subsidy. A kind of reverse auction, it encouraged operators to put in unfeasibly low bids for the prices at which offshore wind farms would generate. While many have heralded the apparently huge drop in offshore costs, no wind farms have actually begun operating at this rate. Industry experts doubt they ever will, suspecting the low offers were a ruse to lock out competition and then blackmail the government on pain of bankruptcy if the price is not raised.

The days where developers saw a prospective wind farm as a licence to print money while policymakers extolled wind energy as clean, green and free are long gone. In the end there is no escaping the laws of physics and engineering, or economics.

In coming years, a great deal of money and attention will have to be spent on improving the resilience of an electricity system undermined by too many remote and intermittent wind farms, and on finding ways to pay the still escalating costs of their subsidy contracts. There will be little appetite for a second wind bonanza whoever is in power.

Two thirds of consumers think connected devices are “creepy”

Consumers are distrustful of how devices collect data about people and their behaviours and more than half don’t trust them to protect privacy.

Two thirds of consumers (65 per cent) are concerned with the way connected devices such as smart meters and personal digital assistants collect data, a new study finds.

 

A similar proportion think connected devices are creepy in the way they collect data about people and their behaviours and more than half (55 per cent) do not trust their connected devices to protect their privacy. More than half (53 per cent) also do not trust connected devices to handle their information responsibly.

 

Basic security concerns

 

The survey by Ipsos Mori on behalf of the Internet Society and Consumers International was conducted in the US, Canada, Japan, Australia, France and the UK.

 

The study noted that testing by multiple consumers organisations has found a range of products are rushed to market with little consideration for basic security and privacy protections.

 

The survey results show that more than three quarters of consumers (77 per cent) across markets said information about privacy and security are important considerations in their buying decisions and more than a quarter of people (28 per cent) who don’t own a connected device don’t buy smart products because of these concerns.

 

Consumers see this broadly as much of a barrier as cost.

 

“The survey results underscore the need for IoT manufacturers to build their devices with security and privacy in mind,” said Andrew Sullivan, president and CEO, Internet Society.

 

“Security should not be an afterthought. It’s clear that manufacturers and retailers need to do more so that consumers can trust their IoT devices.”

 

Those surveyed also believe that accountability for connected device concerns should sit with regulators, manufacturers and retailers.

 

Nine in 10 of survey respondents (88 per cent) said that regulators should ensure Internet of Things (IoT) privacy and security standards, while four-fifths of people (81 per cent) said manufacturers need to provide that assurance, and similar proportion said retailers must address privacy and security.

“Security should not be an afterthought. It’s clear that manufacturers and retailers need to do more so that consumers can trust their IoT devices”

“Consumers have told us they accept that they have some responsibility for the security and privacy of their IoT products but that isn’t the end of the story. They, and we, want to see tangible action from manufacturers, retailers, and governments on this issue.” Added Helena Leurent, director general, Consumers International.

 

She continued: “It has to be a collective effort, not the responsibility of one group. We are exploring this conversation with progressive manufacturers. Together we are looking at the opportunity to create person-centered technology, that people not only enjoy using, but feel safe and secure doing so. By doing this business can address the concerns of those not engaging with this tech, and open up the benefits of the Internet of Things to everyone.”

 

Founded by Internet pioneers, the Internet Society is a non-profit organisation dedicated to ensuring the open development, evolution and use of the Internet.

 

Working through a global community of chapters and members, the Internet Society collaborates with a broad range of groups to promote the technologies that keep the Internet safe and secure and advocates for policies that enable universal access.

BILL BLOW Energy bills could jump by £100 a year despite government cap on prices

The increase comes despite the upcoming introduction of the government’s new price cap in December, which promises to keep costs under control.

Energy regulator, Ofgem, has already signed off a £47 a year increase in its energy safeguard tariff for vulnerable consumers this coming winter.

But energy analyst Cornwall Insight is predicting that both tariff caps could rise by another £50 to £55.

This means that by April next year, we could be paying £100 more on our bills.

Gareth Miller, chief executive of Cornwall Insight said: “Household energy prices are set to continue to rise despite Ofgem’s safeguard tariff or the government’s default price cap.

“Only if wholesale costs fall sharply will the pressure abate.”

Why prices are continuing to rise

Analysts have regularly warned that Ofgem’s price caps will do little to stop energy bill increases.

This is because the level the cap is set at depends on factors such as wholesale prices. As long as these continue to rise, our bills will too.

Stephen Murray, energy expert at comparison website MoneySuperMarket explained: “The price of standard variable tariffs has risen by around £140 on average (from the big six) since the policy announcement of an energy price cap by the government in May 2017.
