In defence of renewables

Huhne is right on climate sceptics and "armchair engineers".

WWF-UK yesterday launched Positive Energy, a report demonstrating that renewable technologies could provide the UK with well over 60 per cent of our electricity needs by 2030; and that we could do this without breaking the bank. The report was welcomed by a wide range of major companies, consumer associations and key commentators. Yet it comes at a time of increased anti-renewable energy sentiment in the media, to the extent that energy secretary Chris Huhne, speaking at the RenewableUK conference today, felt the need to directly rebut the "faultfinders and curmudgeons who hold forth on the impossibility of renewables".

Not only are renewables being blamed as the main reason for energy bill increases, but some outlets are increasingly arguing there is no point in the UK trying to fight climate change: the rest of the world is doing nothing anyway. "Let's focus on shale gas instead", cries the increasingly vocal anti-renewables lobby, claiming that this "wonder gas" will solve all our energy problems. These claims are inaccurate at best, downright disingenuous at worst, and should be seriously challenged.

Saying that renewables are the main driver behind people's bill increases could not be further away from the truth. The wholesale gas price, which rose by 84 per cent between 2004 and 2009, has been the main factor in increasing UK electricity bills by 63 per cent over that same period. Support for renewable technologies has, in contrast, represented only a small fraction of consumer bills to date. Furthermore, the industry is crying out for political certainty to drive costs down, belying the argument that we shouldn't support renewables until their costs drop.

By creating a low-risk environment with clear renewable targets and stable financial support schemes we can reduce the cost of capital, attract companies such as Vestas to invest in renewable energy factories in the UK, incentivise companies to mass produce renewable technologies and increase investment in R&D. All of these are critical to cost reductions -- and to job creation. Look at Germany, which already employs some 367,000 people in its renewable energy industry; something which the UK, which has seen the share of manufacturing per unit of GDP halve in the last 20 years, should surely want to emulate.

On the point that the rest of the world, especially China, is doing nothing to tackle climate change, that again is far from the truth. In terms of investment in renewable energy, the UK -- not even a top-10 world investor -- is playing catch up. According to a recent report from Pew, China is now the world's leading investor and installer of renewable energy, having ploughed over $54bn (£34bn) into renewable energy in 2010 alone;equivalent to the entire world's investment in the sector in 2004.

It's not just compared to China that the UK is lagging behind. Germany and Denmark are already heading towards a 100 per cent renewable electricity future and even Italy and France (well-known for its focus on nuclear) have substantially more renewables than the UK.

Saying that shale gas is the answer to all our energy problems is also fundamentally flawed. Leaving aside the environmental uncertainties around fracking -- such as groundwater contamination and methane gas leakage -- do we really think that relying even more heavily on a single fossil fuel (which already accounts for 80 per cent of our domestic heating and almost half our electricity) is a sensible idea?

Continuing to rely heavily on gas will take the world on a path to at least 3.5C of warming, according to the International Energy Agency. This is almost twice the temperature limit which scientific consensus says we should not exceed if we want to avoid the worst impacts of climate change.

Unfortunately, climate change seems to have completely dropped out of the current energy debate, which is a tragic oversight. Putting aside the catastrophic environmental and human consequences that climate change could trigger, the cost of adapting to a changing climate will absolutely dwarf any of the costs needed today to decarbonise our power sector.

The problems with ending encryption to fight terrorism

Forcing tech firms to create a "backdoor" to access messages would be a gift to cyber-hackers.

The UK has endured its worst terrorist atrocity since 7 July 2005 and the threat level has been raised to "critical" for the first time in a decade. Though election campaigning has been suspended, the debate over potential new powers has already begun.

Today's Sun reports that the Conservatives will seek to force technology companies to hand over encrypted messages to the police and security services. The new Technical Capability Notices were proposed by Amber Rudd following the Westminster terrorist attack and a month-long consultation closed last week. A Tory minister told the Sun: "We will do this as soon as we can after the election, as long as we get back in. The level of threat clearly proves there is no more time to waste now. The social media companies have been laughing in our faces for too long."

Put that way, the plan sounds reasonable (orders would be approved by the home secretary and a senior judge). But there are irrefutable problems. Encryption means tech firms such as WhatsApp and Apple can't simply "hand over" suspect messages - they can't access them at all. The technology is designed precisely so that conversations are genuinely private (unless a suspect's device is obtained or hacked into). Were companies to create an encryption "backdoor", as the government proposes, they would also create new opportunities for criminals and cyberhackers (as in the case of the recent NHS attack).

Ian Levy, the technical director of the National Cyber Security, told the New Statesman's Will Dunn earlier this year: "Nobody in this organisation or our parent organisation will ever ask for a 'back door' in a large-scale encryption system, because it's dumb."

But there is a more profound problem: once created, a technology cannot be uninvented. Should large tech firms end encryption, terrorists will merely turn to other, lesser-known platforms. The only means of barring UK citizens from using the service would be a Chinese-style "great firewall", cutting Britain off from the rest of the internet. In 2015, before entering the cabinet, Brexit Secretary David Davis warned of ending encryption: "Such a move would have had devastating consequences for all financial transactions and online commerce, not to mention the security of all personal data. Its consequences for the City do not bear thinking about."

Labour's manifesto pledged to "provide our security agencies with the resources and the powers they need to protect our country and keep us all safe." But added: "We will also ensure that such powers do not weaken our individual rights or civil liberties". The Liberal Democrats have vowed to "oppose Conservative attempts to undermine encryption."

But with a large Conservative majority inevitable, according to polls, ministers will be confident of winning parliamentary support for the plan. Only a rebellion led by Davis-esque liberals is likely to stop them.
