UK science must fight to make sure it is not an after-thought as Britain renegotiates its relationship with the EU, say research leaders.

From the ‘red-tape’ slashing desires of the Brexiters to the judgment of green professionals, all indications are for weaker environmental protections

Despite being an issue that knows no borders, affects all and is of vital interest to future generations, the environment was low on the agenda ahead of the UK’s historic vote to leave the European Union.

The short answer to what happens next with pollution, wildlife, farming, green energy, climate change and more is we don’t know – we are in uncharted territory. But all the indications – from the “red-tape” slashing desires of the Brexiters to the judgment of environmental professionals – are that the protections for our environment will get weaker.

SLIPPERY PROBLEM: At last a solution to the sticky problem of how to get the last drops of shampoo out of the bottle.

Lower Benefield, Northamptonshire This trickle may be unmapped, but when the water rises, it delivers enough force to damage a bridge

It has no name, but it has torn a bridge apart. “The brook” rises west of Lower Benefield, near Spring Wood. There, a dendritic network of tiny streams converges and flows to Sheepwalk Spinney, after which, for much of the year, the water disappears underground leaving the valley floor dry. Further downstream, around Brook Farm on the eastern side of Lower Benefield, it re-emerges as a wriggly stream that runs all year round. After winding south of Glapthorn, the brook unites with the broad, slow-flowing river Nene near Cotterstock.

Thunderstorms with torrential rain formed flowing sheets of brown water on the roads and saturated the valley this week. Then another storm, and the brook springs into vigorous life, water erupting overground and rising rapidly. Quickly, the stretch upstream of Lower Benefield and the A427 transforms from a trickle between stickleback-occupied pools (we get the three-spined and the scarcer nine-spined) into a tumultuous force; pouring across fields and impelling through spinneys.

SunCrowd says its pioneering program, launched in Newcastle on Thursday, has attracted keen interest

Australia’s first bulk-buy program for solar battery storage has launched, with more than 1,000 people in Newcastle expressing interest and more than 500 attending a sign-up event on Thursday night to buy home battery systems. From Friday, the program is being opened to people all around Australia.

The cost and complexity of battery storage, and the expectation that prices will come down , has so far discouraged purchases.

The federal election campaign has highlighted the very different visions of Australia’s renewable energy future held by the major parties. The Coalition government supports the present Renewable Energy Target (RET) of 33,000 gigawatt-hours from large-scale projects in 2020, which it negotiated with the Labor opposition in 2015.

It’s expected to deliver just over a 23% contribution of renewables to the Australian electricity sector in 2020. There is, most likely, only one more federal election before then.

For the longer term, the Coalition proposes no change to this target before 2030 which, given future demand growth, might well see renewables' contribution to Australian electricity supply actually fall.

By comparison, Labor has a target of 50% renewable electricity by 2030 and the Greens a 90% target. Complicating the situation further are the ambitious targets of some state and territory governments.

Targets require means to actually achieve them. The RET is a target, but also a mechanism based around trading in Renewable Energy Certificates. Meeting the agreed 2020 target requires new renewable energy generation to provide these certificates.

The Clean Energy Council estimates that an additional 6,000 megawatts of new renewable generation, requiring around A$10 billion of investment, will be required by 2020.

The new generation and investment required to meet Labor or the Greens' far more ambitious 2030 targets is, of course, far greater.

Energy for the people

Community renewable energy (CRE) may have a key role to play. Community energy can involve supply-side projects such as renewable energy installations and storage, and demand-side projects such as community education, energy efficiency and demand management.

In short, community renewable energy revolves around community ownership, participation, and consequent benefits from community-scale renewable energy projects.

Why would these small-scale projects matter for reaching ambitious renewable energy targets? Surely large industry players are better placed to develop renewables than the community?

Perhaps, but the transition to a renewable energy future will almost certainly require high levels of social consensus and engagement, and community renewable energy can play a key role in building this.

The 2016 edition of the highly authoritative Renewables Global Status Report has just been released, and includes a special chapter on CRE.

If we consider industrialised countries with major progress on renewable energy over the past few decades and ambitious future targets, community energy seems to have played a key role in a number of them.

For example, Denmark has already nearly reached its 50% target for renewable electricity by 2020 and was a pioneer in community energy, beginning in the late 1970s.

Germany reached 32% renewable electricity in 2015 with a target of 40% to 45% by 2025, and has some 850 energy cooperatives. Almost half of its installed capacity is owned by households, communities and farmers.

Community ownership has become a well-established part of the renewable energy sector, and to the energy transition in western countries such as Germany, Denmark, Britain and, increasingly, the United States.

But it is still a fairly new concept to Australia.

Australia’s Renewable Energy Target

One reason for this may be the design of our RET itself.

It is actually two schemes: one specifically tailored for households and small business, and the other for far larger-scale projects.

As a result, Australia’s renewable landscape is characterised by large utility-sized projects, mostly wind, hydro and bioenergy. Large-scale solar now looks to be taking off too.

At the other end of the spectrum are some 1.5 million household solar photovoltaic (PV) systems; indeed, Australia has the most household PV systems per person in the world.

Community renewable projects, by comparison, are usually mid-sized. They lack the economics of larger renewable projects, and the targeted RET support and simple PV grid connection available to households.

Do we need them given the community’s enthusiastic embrace of household PV? Well, not all households have a roof to call their own on which they can install a PV system. For example, 14% of Australians live in apartments. There are also other promising renewable opportunities such as mid-sized wind and biomass projects whose deployment is generally beyond the capabilities of individuals.

Australia’s small but growing community movement with over 70 groups and more than 30 operating projects, would certainly seem to highlight the opportunity that now presents itself here – and raises the question of what governments might do to assist them.

Building support

International experience highlights that a range of policy support and other initiatives are a prerequisite for community energy success. Communities often lack the funding, knowledge, capacities or network to organise and construct a project. Specific support for community energy can help reduce risks, build community capability and increase the economic viability of these projects.

Indeed, it is interesting to note that recently announced, more market-focused, changes to the German Renewable Energy Act are being widely criticised because of their likely adverse impacts on community renewable energy.

In Australia, Labor has pledged A$98.7 million and the Greens a total of A$265.2 million to support CRE projects ahead of the election.

Both commitments include support to provide local groups with technical, legal and administrative expertise as seen in so-called “community powerhouses”, which are modelled on the Moreland Energy Foundation. Funding for a network of these new support organisations could help to leverage the efforts of community members, local governments and private business towards CRE projects.

The Greens' plan also comprises a range of other initiatives such as tax incentives to support the emerging community renewable energy sector.

The Coalition, by comparison, has pledged A$5 million for grants of up to A$15,000 to community groups to install rooftop PV, solar hot water, other small-scale renewables, and battery energy storage systems, as part of their Solar Communities program.

This might seem strange given the opportunity for CRE to create rural and regional investment and jobs. The Green Tea Party movement in the United States highlights that even the most conservative can get behind community renewables.

Importantly, experience in Australia and elsewhere shows that we need to revisit electricity market arrangements, including regulations governing connection and network tariffs, to facilitate CRE. Our research (just accepted for publication in the Journal of Energy Research & Social Science) has also highlighted that local governments can play a key role in supporting community engagement with renewable energy.

Given the opportunity to spread the benefits of renewables more broadly across the community, we really need all levels of government to get involved.

Dark bordered beauty moths have declined by over 90% at their last stronghold near York due to sheep grazing and habitat loss

The dark bordered beauty moth is heading towards extinction at its last site in England, new research has found.

The tiny, rare insect is now found only on Strensall Common, an area of protected lowland heath near York, having been lost from Newham Bog in Northumberland. But scientists have found that even in its last stronghold numbers have plunged by over 90% in the last seven years, with only 50-100 thought to remain.

Cook et al. (2013) has remained the most-read paper in Environmental Research Letters for most of the past 3 years

In 2013, a team of citizen science volunteers who collaborate on the climate myth debunking website SkepticalScience.com published a paper finding a 97% expert consensus on human-caused global warming in peer-reviewed research. Over the past 3 years, that paper has been downloaded more than 500,000 times. For perspective, that’s 4 times more than the second-most downloaded paper in the Institute of Physics journals (which includes Environmental Research Letters, where the 97% consensus paper was published).

The statistic reveals a remarkable level of interest for a peer-reviewed scientific paper. Over a three-year period, the study has been downloaded an average of 440 times per day, and the pace has hardly slowed. Over the past year, the download rate has remained high, at 415 per day.

EPA has been reviewing lead and copper rule since 2010 but has yet to make changes even as its own scientists have criticized current regulations

Changes to laws that protect Americans’ drinking water are still at least six months away, the US Environmental Protection Agency has said, despite the ongoing lead crisis in Flint and calls for reform from lawmakers and public health groups.

The EPA has been reviewing the lead and copper rule, part of the Safe Drinking Water Act, since roughly 2010. The rule is supposed to ensure high levels of lead don’t seep into drinking water, but has been the subject of criticism for years by scientists who feel it has not adequately protected the public.

Sandy, Bedfordshire A queen hit the bullseye – a 2.8cm hole in our nestbox – and there is a clearly active colony of tree bumblebees in residence

Since the start of the millennium, a new tune for summer has been spreading north. It was first picked up in Wiltshire; within a decade, it had reached southern Scotland. I can hear it from the bathroom, the bedroom, or standing under the eaves at the back door. The sound is not discernibly different from that made by the maker’s nearest relatives, though the animal’s habits certainly are.

We know this newbie as the tree bumblebee. Common on the continent, it flew the Channel, as wild creatures are apt to do, though we rarely understand why they choose a certain time to move. Most bumblebees nest underground. The tree bumblebee, with a taste for high living, has taken to birdboxes.
