A pilot project to turn 10 homes in Nottingham into net-zero emission properties without residents even moving out is nearing completion.
Developer Melius Homes and social landlord Nottingham City Homes have worked together on the scheme, with UK solar manufacturer Viridian Solar providing photovoltaic roofing.
The upgrades also include better insulated outside walls and upgraded heating systems.
After the refurbishment, tenants will pay an energy services fee instead of paying for gas and electricity.
With this guaranteed additional income, to which savings on planned maintenance costs are added, the landlord can borrow enough money to fund the upfront costs.
The goal is to drive better economies of scale so the work can be completed at an attractive price requiring no government support.
Stuart Elmes, CEO of Viridian Solar, said: “The opportunity it offers to completely regenerate whole areas of our towns and cities, increasing the value of property and improving the comfort of tenants, all financed by energy savings is amazing.”
The 10 homes in Nottingham are a pilot study, with an option to extend the programme to 400 more.
#EarthOvershootDay has arrived. The world has consumed more natural resources than the world can renew throughout the whole of the year.
We use more ecological resources and services than nature can regenerate through overfishing, overharvesting forests, and emitting more carbon dioxide into the atmosphere than forests can sequester.
Global Footprint Network, an international research organization, is marking Earth Overshoot Day this year with the launch of a new mobile-friendly Footprint calculator. Try it out yourself at www.footprintcalculator.org.
The new Footprint Calculator allows users to measure their own demand on nature (Ecological Footprint) and assess their personal Earth Overshoot Day. A user’s personal Earth Overshoot day is the date Earth Overshoot Day would be if all people had their Footprint.

CEF FFT: Imagine if everyone in the world knew what their personal footprint was on the planet! What kind of impact could this awareness bring?
Take a look at this twisting, smog-eating tower that is going up in Taipei, Taiwan.
On the outside, 23,000 trees and shrubs – nearly the same amount found in New York’s Central Park – will fill the skyscraper’s facade, roof, and balconies. And inside, it will feature 40 luxury condos.
The plants will absorb 130 tons of carbon dioxide emissions per year – the equivalent of about 27 cars, lead designer Vincent Callebut tells Business Insider.
Called the Tao Zhu Yin Yuan Tower , it’s set to open by September 2017.
CEF FFT: Imagine what cities could look like (not too far) in the future if we set new municipal standards that increased our sustainability and environmental health!

This is NET Power’s prototype plant near Houston, Texas. It is testing an emission-free technology designed to compete with conventional fossil power.
Zero-emission fossil fuel power sounds like an oxymoron. But when that 25-megawatt demonstration plant is fired up later this year, it will burn natural gas in pure oxygen. The result: a stream of nearly pure CO2, which can be piped away and stored underground or blasted into depleted oil reservoirs to free more oil, a process called enhanced oil recovery (EOR). Either way, the CO2 will be sequestered from the atmosphere and the climate.
That has long been the hope for carbon capture and storage (CCS), a strategy that climate experts say will be necessary if the world is to make any headway in limiting climate change. But CCS systems bolted to conventional fossil fuel plants have struggled to take off because CO2 makes up only a small fraction of their exhaust. Capturing it saps up to 30% of a power plant’s energy and drives up the cost of electricity.
In contrast, NET Power, the startup backing the new plant, says it expects to produce emission-free power at about $0.06 per kilowatt-hour. That’s about the same cost as power from a state-of-the-art natural gas-fired plant—and cheaper than most renewable energy. The key to its efficiency is a new thermodynamic cycle that swaps CO2 for the steam that drives turbines in conventional plants. Invented by an unlikely trio—a retired British engineer and a pair of technology geeks who had tired of their day jobs—the scheme may soon get a bigger test. If the prototype lives up to hopes, NET Power says, it will forge ahead with a full-scale, 300-megawatt power plant—enough to power more than 200,000 homes—which could open in 2021 at a cost of about $300 million. Both the company and CCS experts hope that the technology will then proliferate. “This is a game-changer if they achieve 100% of their goals,” says John Thompson, a carbon capture expert at the Clean Air Task Force, an environmental nonprofit with an office in Carbondale, Illinois.
Even if NET Power’s technology works as advertised, not everyone will be a fan. Lukas Ross, who directs the climate and energy campaign at Friends of the Earth in Washington, D.C., notes that the natural gas that powers the plant comes from hydraulic fracturing, or “fracking,” and other potentially destructive practices. And providing a steady supply of high-pressure gas for EOR, he adds, will only perpetuate a reliance on fossil fuels. Ross argues that money would be better spent on encouraging broad deployment of renewable energy sources, such as solar and wind power.
Yet oddly enough, NET Power could help smooth the way for renewables to expand. The renewable portfolio standards in many countries and U.S. states require solar, wind, and other carbon-free sources to produce an increasing proportion of the electric power supply. But those sources are intermittent: The power comes only when the sun is shining and the wind is blowing. Nuclear and fossil fuel sources provide “base load” power that fills the gaps when renewables aren’t available. Conventional natural gas power plants, in particular, are viewed as a renewable-friendly technology because they can be ramped up and down quickly depending on the supply of renewable power.
CEF FFT: Although this is not an ideal solution, perhaps this is a step in the right direction. Who knows what this new Allam Cycle could inspire in other renewables.

A coal-powered plant in Tuticorin, India has found an innovative way to capture carbon emissions — by recycling them into soda ash, an ingredient in common household products like bleach, sweeteners, and even your toothpaste.
The typical carbon capturing method filters out the carbon before it is released into the atmosphere and stores it in a separate containment. But Tuticorin is changing it up by crystallizing the coal and turning it into soda ash — otherwise known as baking soda.
That baking soda byproduct means Tuticorin has made carbon capture profitable: Not only is it environmentally wise, but dirty waste is being re-imagined to sell plastic, rubber, or glass manufacturing.
With solar, wind, and hydropower resources becoming more accessible to the masses, the demand for natural gas is expected to be on the decline, making this carbon capture method attractive to businesses and consumers alike. According to the Ren21 Global Status Report for 2015, the world invested twice as much in clean energy as they did in the oil and gas industry. Previous roadblocks have stopped the U.S. from investing in carbon capture in the past. But this new mechanism can be outfitted to any plant — no matter how old — and is much more affordable.
