Theresa May Urges G20 Countries to Target Zero Emissions
Theresa May, the outgoing UK prime minister, used her final appearance at the G20 summit in Osaka, Japan to urge other nations to follow her country's lead in aggressively lowering greenhouse gas emissions.
The prime minister, who led a session on the environment at the G20 summit, asked the other countries to set a target date for net zero emissions, following the UK's example of becoming a net zero emitter of all greenhouse gas emissions by 2050, according to the BBC.
The UK is committed either to eliminate greenhouse gas emissions completely or, in rare cases, to offset them by planting trees or absorbing carbon dioxide from the atmosphere.
"In recent months we have heard hundreds of thousands of young people urge us — their leaders — to act on climate change before it's too late," she said at the end of the summit, as the Guardian reported. "I am proud that the UK has now enshrined in law our world-leading net zero commitment to reduce emissions. And I have called on other countries to raise their ambition and embrace this target."
While other countries did not sign on to May's target, she did push for strong wording in a communiqué from the summit. The final product was a watered down commitment to meet the targets of the Paris climate agreement, which 19 of the 20 participating countries signed. The U.S. was the lone holdout. Under the Paris agreement, every nation is committed to keeping global temperature rises to less than 2 degrees Celsius (3.6F) higher than pre-industrial times.
May said she was pleased there was a communiqué at all, according to the Guardian.
President Trump's unwillingness to commit to cutting greenhouse gas emissions forced the participating nations to add a clause that exempted the U.S. from joining in, as Sky News reported.
"The United States reiterates its decision to withdraw from the Paris Agreement because it disadvantages American workers and taxpayers," the clause read.
Throughout the summit, President Trump dismissed the worldwide push for climate action and denied that any aggressive response to curb the world's greenhouse gas emissions was necessary. He also seemed not to understand the difference between climate change and air pollution.
"We have the cleanest water we have ever had. We have the cleanest air we've ever had, but I'm not willing to sacrifice the tremendous power of what we've built up over a long period of time and what I've enhanced and revived," Trump said at a news conference.
In that same news conference, he dismissed renewable and clean sources of energy as inefficient without citing evidence.
"I'm not sure that I agree with certain countries with what they are doing. They are losing a lot of power. I am talking about the powering of a plant," he said, as the Washington Post reported. "It doesn't always work with a windmill. When the wind goes off, the plant isn't working. It doesn't always work with solar because solar [is] just not strong enough, and a lot of them want to go to wind, which has caused a lot of problems."
Trump's comments and inaction raised the hackles of environmental action groups and scientists.
"While other leaders managed to hold the line on the Paris agreement, it's unfortunate that they have to continually fight this rear-guard action against Trump denialism instead of devoting their energies to scaling up global action," said Elliot Diringer, executive vice president of the Center for Climate and Energy Solutions, as the Washington Post reported.
"Trump is ignoring not only science but the growing demands of the U.S. public and U.S. companies for decisive action. As even the Chamber of Commerce recently declared, inaction is not an option."

More long-finned pilot whales were found stranded today on beaches in Tasmania, Australia. About 500 whales have become stranded, including at least 380 that have died, the AP reported. It is the largest mass stranding in Australia's recorded history.

By 2030, almost a third of all the energy consumed in the European Union must come from renewable sources, according to binding targets agreed in 2018. Sweden is helping lead the way.

Naturally Warm<p>54% of Sweden's power comes from renewables, and is helped by its geography. With plenty of moving water and 63% forest cover, it's no surprise the <a href="https://sweden.se/nature/energy-use-in-sweden/#" target="_blank">two largest renewable power sources</a> are hydropower and biomass. And that biomass is helping support a local energy boom.</p><p>Heating is a key use of energy in a cold country like Sweden. In recent decades, as fuel oil taxes have increased, the country's power companies have turned to renewables, like biomass, to fuel local 'district heating' plants.</p><p>In Sweden these trace their <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank">origins back to 1948</a>, when a power station's excess heat was first used to heat nearby buildings: steam is <a href="https://www.sciencedirect.com/topics/engineering/district-heating-system" target="_blank">forced along a network of pipes</a> to wherever it's needed. Today, there are around 500 district heating systems across the country, from major cities to small villages, providing heat to homes and businesses.</p><p>District heating used to be fueled mainly from the <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140" target="_blank">by-products of power plants</a>, waste-to-energy plants and industrial processes. These days, however, Sweden is bringing more renewable sources into the mix.

Sweden is using smart grids to turn buildings into energy producers. Huang et al/Elsevier
Energy ‘Prosumers’<p>But Sweden doesn't stop at village-level heating solutions. Its new breed of energy-generation takes hyper-local to the next level.</p><p>One example is in the city of Ludivika where 1970s flats <a href="https://www.buildup.eu/sites/default/files/content/transforming-a-residential-building-cluster-into-electricity-prosumers-in-sweden.pdf" target="_blank">have recently been retrofitted with the latest smart energy technology</a>.</p><p>48 family apartments spread across 3 buildings have been given photovoltaic solar panels, thermal energy storage and heat pump systems. A micro energy grid connects it all, and helps charge electric cars overnight.</p><p>The result is a cluster of 'prosumer' buildings, producing rather than consuming enough power for 77% of residents' needs. With <a href="http://www.diva-portal.org/smash/get/diva2:1232060/FULLTEXT01.pdf" target="_blank" rel="noopener noreferrer">high levels of smart meter usage</a>, it's a model that looks set to spread across Sweden.</p>

The system is not only more efficient, but bills have fallen.</p><p>Smart energy developments like those in Hyllie, Ludivika, and renewable-driven district heating, offer a radical alternative to the centralized energy systems many countries rely on today.</p><p>The EU's leaders have a challenge: how to generate 32% of energy from renewables by 2030.
