Technology firm hailed success of machine-learning trial and said efficiencies will be applied to all its centres by end of year

Google says it has cut its vast data centres’ energy use by 15% by applying artificial intelligence to manage them more efficiently than humans.

The servers that power billions of web searches, streamed films and social media accounts are estimated to account for around 2% of global greenhouse gas emissions. Google is believed to have one of the biggest fleets of them in the world.

Greenpeace urges legal ban to tackle problem after finding that top personal care companies fell short on commitments

Loopholes in the voluntary pledges by the biggest personal care companies to phase out polluting microbeads have been revealed in a report from Greenpeace, which says a legal ban is needed.

Tiny plastic beads are widely used in toiletries and cosmetics but thousands of tonnes wash into the sea every year, where they harm wildlife and can ultimately be eaten by people, with unknown effects on health. A petition signed by more than 300,000 people asking for a UK ban was delivered to the prime minister in June A US law banning microbeads was passed at the end of 2015.

Maria Damanaki questioned feasibility of UK controlling stocks or setting its own catches without input from Europe

The EU’s former fisheries chief has said it is an illusion that the UK will be able to dictate its fishing policies after Brexit.

Maria Damanaki, the former commissioner for fisheries, who oversaw the most sweeping reforms of the EU’s common fisheries policy in decades, said: “The idea that you can control fisheries at a national level is an illusion for any country, but especially the UK - with Brexit or without. International cooperation is needed to keep stocks and control.”

The World Bank is poised to support a new coal plant that would modernise Kosovo’s creaking energy infrastructure, but also lock the young nation into a future powered by a regressive fossil fuel

In the early days of December 2015, as the Paris climate talks veered off course and off schedule, the US secretary of state John Kerry left his team of negotiators and flew to Kosovo to voice his support for a proposed US-built, World Bank-sponsored coal power station.

Speaking alongside the prime minister, Isa Mustafa, Kerry told reporters at Pristina airport that the Kosovo e re (New Kosovo) plant would help the tiny, impoverished country do “its part to contribute to this global effort of nations who are committed to dealing with climate change” by replacing an extremely high-polluting cold war-era power plant. Kerry then returned to Paris and helped land a deal intended to bring the fossil fuel era to an end.

A former UK energy minister claims the offshore wind industry in Scotland is "pretty much dead" after a legal challenge to four projects.

Britain has lost more than 70 percent of its cuckoos in the last 25 years, but tiny tracking devices fitted to some of the birds may have solved the mystery of their decline.

THE X FACTOR: An enormous X-shaped structure made of stars lies at the centre of the Milky Way, indicates a new study of infrared light coming from our home galaxy.

When Victorian Premier Daniel Andrews reshuffled his cabinet in May, most of the headlines were about Wade Noonan’s return after suffering mental health issues, and Lisa Neville who became the state’s first female police minister.

But from an environmental perspective there was another significant change. Energy and resources, long regarded as twin portfolios, were split. Instead, the energy brief was partnered with climate change and environment under a single minister, Lily D’Ambrosio.

On Monday, Prime Minister Malcolm Turnbull followed suit, creating a new super-portfolio of environment and energy, with Josh Frydenberg as the minister.

Linking policy development and decision-making for the energy and climate change portfolios makes sense. As a result of the historic Paris Agreement struck last year, the world – including Australia – is committed to achieving net zero emissions by 2050.

This calls for a major transformation, shifting the world’s energy away from fossil fuels and towards renewable sources like solar and wind, newer technologies such as wave and geothermal energy, and innovations like battery storage and energy demand management.

In that sense, energy and climate (and therefore the environment) go hand in hand. Decisions about energy sources have direct implications for our ability to deal with climate change. Conversely, decisions taken to reduce emissions will invariably impact on the energy portfolio. The two sectors have been crying out for better integration.

Many of the technologies needed to decarbonise our electricity system are already available. But we need to move faster. Our research at ClimateWorks Australia shows we will need at least 50% renewable electricity by 2030 if we are to decarbonise the electricity sector in time to avoid the worst effects of climate change.

This means we need policies that will push harder to help large-scale clean energy technologies reach the necessary level of commercialisation and integration.

Renewables and efficiency

Within these broad portfolios, there are particular policy areas that also need to be linked more closely with one another. In particular, renewable energy policy needs to be combined with measures to promote energy efficiency.

There is a natural synergy between renewable energy and energy efficiency, yet the two have never been systematically linked at either a national or state level. The better our energy efficiency performance, the less investment we need in new renewable energy sources to replace carbon-intensive ones. This in turn helps to lower the overall network costs and can protect households against rising power bills.

While unit prices of electricity are expected to rise as we modernise and decarbonise the energy system, household bills need not. If governments promote energy efficiency at the same time, households can reduce their energy use to offset the rising energy costs, keeping bills flat or even reducing them.

The lack of joined-up thinking between these two areas has led to missed opportunities. Some 1.5 million Australian homes have solar panels, thanks in part to the federal incentive scheme. Meanwhile, there are separate state-based incentive schemes for household energy efficiency. Why have these two never been linked? If solar panel installers could also provide household energy efficiency audits, householders could kill two birds with one stone and further reduce their demands on the electricity grid.

Household battery storage technology provides the next key opportunity to link installation incentives with renewable energy and energy efficiency. But this opportunity will again be missed if policies are not better integrated within the portfolio.

The National Energy Productivity Plan is a new policy with 34 measures aimed at improving energy efficiency. Frydenberg led this process when he chaired the COAG Energy Council last year. He has retained these responsibilities within his expanded portfolio, giving him a golden opportunity to take a truly integrated approach.

In the meantime, D’Ambrosio has taken the opportunity to review Victoria’s upcoming action plans on renewable energy and energy efficiency, to take advantage of the opportunity in her joint portfolio to ensure energy and climate policies have the close integration they need.

Whole-of-government support

Of course, integrating the energy and climate portfolios is not the whole solution. Cabinet support will still be needed to introduce integrated policies in other areas that are critical to hitting Australia’s emissions reduction targets. Examples include: putting specific regulations on emissions-intensive industries; creating market enablers for low-carbon technologies; ratcheting up green standards for buildings, vehicles and infrastructure; and ensuring planning approval systems are designed to take account of these targets.

The real work will need to happen in the federal government’s 2017 review of policies to achieve Australia’s Paris emissions target of 26-28% below 2005 levels by 2030. A recent Pricewaterhouse Coopers report found that “Australia will need to nearly double its historic rate of decarbonisation, to 4.4% annually”, if it is to meet even the lower end of this goal.

Ministers often talk about taking a “whole-of-government approach” to major issues. Yet plenty of silos still need breaking down if we are to achieve meaningful action on climate change.

The moves in both Canberra and Spring Street to bring environment, climate and energy under a single umbrella are a positive step towards better policy and real action. But, as ever, there is still plenty of hard work ahead.

Government says carbon storage technology not cost-efficient, while critics say U-turn will double cost of tackling climate change

The government’s cancellation of a pioneering £1bn competition to capture and store carbon emissions may have pushed up the bill for meeting the UK’s climate targets by £30bn, according to a report from the UK’s official spending watchdog.

The National Audit Office (NAO) report, published on Wednesday, says the move has delayed by a decade the deployment of carbon capture and storage (CCS) technology in the UK, which takes emissions from power stations and industry and buries them so they do not contribute to global warming.

Bolt Head, South Devon This Finnish windjammer loaded with thousands of tons of grain had reached Falmouth from south Australia in just 86 days

Eighty years ago the cliff-land here was thronged with curious sightseers, including my grandfather and uncle who drove from St Dominic to view the wreck of the Herzogin Cecilie with its masts towering towards the spectators. This Finnish windjammer – a four-masted barque loaded with thousands of tons of grain – had reached Falmouth from the Boston Island anchorage in south Australia in just 86 days, but on the last lap towards Ipswich it foundered on the Ham Stone off Soar Mill Cove.

Hosegoods, the Plymouth grain merchants, salvaged damp wheat, and my grandfather bought some cheaply for delivery to Cotehele Mill via the river Tamar and his barge, the Myrtle. It was mixed with extra-dry Persian barley, made into pig and poultry meal, and sold to local farmers.

The Australia Institute says gas are generators are driving "obscene" power price spikes by choosing to exploit an energy market failure, rather than fulfil their role of complementing renewables.

Front page "exclusive" on The Australian about wind energy is so spectacularly wrong that it might make you laugh, were it not for the fact that so many conservatives swallow this tripe.

Solar power and battery storage are already challenging conventional electricity generation and distribution models. This transition to clean energy is happening in spite of government policy, not because of it.
