How is Energy and Science paving the way for cleaner renewable energy sources in 2016 and beyond?

 

The face of energy is changing: traditional fossil fuel sources are giving way to a future reliant on more renewable energy.

 

But that means that renewable energy must also change -right?

 

To be viable in the long term, renewable energy sources must be more powerful and cost-effective.

Here are five avenues researchers are exploring in an effort to make that more renewable future a reality.

 

1. Solar Power:Building better solar solutions

 

Solar energy has been around for decades, but in recent years it has been receiving more funding and interest than ever. That attention is coming from both the public and private sectors. In September, the U.S. Department of the Navy made its largest renewable investment to date through a solar farm partnership with Sempra and the Western Area Power Administration, while massive private companies across various fields from Apple and Cisco to Kaiser Permanente are investing in solar to the tune of billions.

That increased interest in solar means increased interest in making solar better. The U.S. Department of Energy (DoE) launched the SunShot initiative in 2010 with the goal of making solar energy cost-competitive: five years in, the initiative has made significant strides forward and is funding further advancements. In January 2016, the DoE assigned $18 million in funding to six projects across the country developing more scalable and cost-efficient solar energy storage technologies as part of its Grid Modernization Initiative (a sector of the SunShot Initiative).

2. Wind Power: taking wind farms to the next level

 

Wherever there are wide open spaces, there are opportunities for wind power. It’s a rapidly growing field—wind power provides 4.2 percent of Australia’s overall electricity, and approximately 5 percent of energy needs in both Canada and the United States. But as those numbers aim to increase, engineers are searching for ways to maximize power generation in finite space.

One potential breakthrough is high altitude wind power, harnessing the more forceful winds of the upper atmosphere to generate energy. Startups like Altaeros Energies are experimenting with methods like turbines built into helium-filled industrial blimps, with the claim that these high-altitude methods could generate twice as much power compared to conventional wind turbines.

3. Nuclear Energy: Nuclear is clean, affordbale and secure we hope.

 

The thought of nuclear energy often gives consumers pause. But in fact, it’s much more common than the average consumer would think. According to the DoE, 20 percent of the country’s power generation in the last two decades has come from a nuclear power source, making it by far the largest current source of non-greenhouse-gas-emitting power generation. The energy community is also working hard on initiatives to expand the capabilities of this alternative energy source while also making it safer and more secure.

As a result of research by Advanced Reactor Concepts (ARC), nuclear energy will continue to provide clean, affordable, and secure energy while supporting the administration’s greenhouse gas reduction goals by introducing advanced designs into new energy and industrial markets,” states a recent report from the DoE’s office of nuclear energy. This research includes the development of “next generation” nuclear plants, from safer accident-containing sites to “recycling” reactors that turn previous nuclear waste into new fuel to power the future.

4, Tidal Power: Harnessing tidal for energy

 

From conventional oil exploration to offshore wind farms, the ocean is home to myriad energy projects. It is also the very source of a progressive generation approach called tidal power. Referred to as a “sister resource” to wind power, tidal power uses floating hydraulic pumps and the perpetual motion of ocean currents to generate energy.

While tidal power has raised some concerns and detractors are still unconvinced of its potential, the method is gaining significant traction as a viable option in coastal regions, especially industrial regions where other forms of energy production are falling out of favor. In these areas, populations are looking to tidal power as a source for both renewable energy and a refreshed job market.

5. Carbon Capture: Capturing Carbon Dioxide - CO2 

 

Environmental issues like climate change have long been linked to an accumulation of greenhouse gases like carbon dioxide in the atmosphere. But what if that carbon could be captured and repurposed as something beneficial? Researchers are currently looking into ways to recapture carbon from fossil fuels like coal and reuse the resource as a cost-effective energy source. Unlike some other forms of renewable energy, these researchers recognize that carbon capture may not be the greenest solution immediately—but with time its effects can be unlocked.

"In the short term, in order to develop the technology, we probably will enable more use of hydrocarbons, which makes environmentally conscious people uncomfortable,” Chris Jones, a chemical engineer studying CO2 capture at the Georgia Institute of Technology, told David Biello in a report for Yale 360. “But it’s a necessary thing we have to do to get the technology out there and learn how to make it more efficient.

All but two UK regions failing on school energy efficiency

Yorkshire & the Humber and the North East are the only UK regions where schools have collectively reduced how much they spend on energy per pupil

Most schools are still "treading water" on implementing energy efficient technology, according to new analysis of Government data from eLight.

Yorkshire & the Humber and the North East are the only regions where schools have collectively reduced how much they spend on energy per pupil, cutting expenditure by 4.4% and 0.9% respectively. Every other region of England increased its average energy expenditure per pupil, with schools in Inner London doing so by as much as 23.5%.

According to The Carbon Trust, energy bills in UK schools amount to £543 million per year, with 50% of a school’s total electricity cost being lighting. If every school in the UK implemented any type of energy efficient technology, over £100 million could be saved each year.

Harvey Sinclair, CEO of eEnergy, eLight’s parent company, said the figures demonstrate an uncomfortable truth for the education sector – namely that most schools are still treading water on the implementation of energy efficient technology. Energy efficiency could make a huge difference to meeting net zero ambitions, but most schools are still lagging behind.

“The solutions exist, but they are not being deployed fast enough," he said. "For example, we’ve made great progress in upgrading schools to energy-efficient LED lighting, but with 80% of schools yet to make the switch, there’s an enormous opportunity to make a collective reduction in carbon footprint and save a lot of money on energy bills. Our model means the entire project is financed, doesn’t require any upfront expenditure, and repayments are more than covered by the energy savings made."

He said while it has worked with over 300 schools, most are still far too slow to commit. "We are urging them to act with greater urgency because climate change won’t wait, and the need for action gets more pressing every year. The education sector has an important part to play in that and pupils around the country expect their schools to do so – there is still a huge job to be done."

North Yorkshire County Council is benefiting from the Public Sector Decarbonisation Scheme, which has so far awarded nearly £1bn for energy efficiency and heat decarbonisation projects around the country, and Craven schools has reportedly made a successful £2m bid (click here).

The Department for Education has issued 13 tips for reducing energy and water use in schools.
