Nuclear Power ‘Cannot Rival Renewable Energy’

nuclear power plantNuclear power is in terminal decline worldwide and will never make a serious contribution to tackling climate change, a group of energy experts argues.

Meeting recently in London at Chatham House, the UK’s Royal Institution of International Affairs, they agreed that despite continued enthusiasm from the industry, and from some politicians, the number of nuclear power stations under construction worldwide would not be enough to replace those closing down.

The industry was disappearing, they concluded, while the wind and solar sectors were powering ahead. Continue reading “Nuclear Power ‘Cannot Rival Renewable Energy’”

Breakthrough innovation enables cheaper solar energy production

solar energy breakthroughWhile the need for renewable energy around the world is growing exponentially, Lithuanian and German researchers have come up with a novel solution for developing low-cost solar technology. Material, synthesised by Kaunas University of Technology (KTU) Lithuania scientists, which self-assemble to form a molecular-thick electrode layer, presents a facile way of realising highly efficient perovskite single-junction and tandem solar cells. The licence to produce the material has been purchased by a Japanese company.

According to scientists, achieving perovskite-based solar cells, combining low price and high efficiency, has proven to be a difficult endeavour in the past. The particular challenge in large-scale production is the high price and limited versatility of the available hole-selective contacts. KTU chemists have addressed this challenge.

German renewable energy output surges on offshore wind updraft

offshore windGermany’s offshore wind power production has surged by almost 25% this year, or 24TWh, up from 19.5TWh in 2018, helping to carry the share of renewables in Europe’s largest economy to 43% of its gross power consumption.

That was up from 38.2% in 2018, preliminary figures from solar and hydrogen research centre Baden-Württemberg (ZSW) and the German federation of energy and water industries (BDEW) show. Continue reading “German renewable energy output surges on offshore wind updraft”

Report: Renewable Energy to Expand by 50% in Next Five Years

Global supplies of renewable electricity are growing faster than expected and could expand by 50% in the next five years, powered by a resurgence in solar energy.

The International Energy Agency (IEA) found that solar, wind and hydropower projects are rolling out at their fastest rate in four years.

Its latest report predicts that by 2024 a new dawn for cheap solar power could see the world’s solar capacity grow by 600GW, almost double the installed total electricity capacity of Japan. Overall, renewable electricity is expected to grow by 1,200GW in the next five years, the equivalent of the total electricity capacity of the US. Continue reading “Report: Renewable Energy to Expand by 50% in Next Five Years”

More Renewables Than Fossil Fuels: The U.K. Reaches an Energy Milestone

Renewable energy has made a breakthrough in the U.K. The third quarter of this year was the first where more electricity was generated from renewable sources than from fossil fuels.

According to new analysis by the climate change analysis site Carbon Brief, Q3 saw 40% of power come from renewables such as wind, biomass and solar, while fossil fuels—almost all gas, as coal and oil now have a negligible share of the U.K. energy scene—accounted for 39% of generation. (The remaining 21% largely came from nuclear.) Continue reading “More Renewables Than Fossil Fuels: The U.K. Reaches an Energy Milestone”

Breathing new life into renewable energy

Green technology has come a long way. The next challenge for the US National Renewable Energy Laboratory is to develop ways to recycle the recycling infrastructure.

The clean energy sector faces a major stumbling block. The power it produces may be renewable, but the infrastructure it uses is far from it.

Over the past decade, advances in composite materials have allowed the construction of enormous turbine blades. Some are now longer than the wingspan of a Boeing 747. As blades have increased, so have the costs to transport them. When wind farms need to replace aging blades, it is now often cheaper to leave them lying on the ground. Continue reading “Breathing new life into renewable energy”

Twenty UK universities have agreed £50m deal to buy renewable energy from British windfarms

Twenty of the UK’s leading universities have struck a £50m deal to buy renewable energy directly from British windfarms for the first time.

The collaborative clean energy deal will supply electricity from wind farms across Scotland and Wales to universities including Newcastle University, University of Exeter and Aberystwyth University.

The landmark deal, known as a “power purchase agreement” or PPA, is the first time that public sector energy users have clubbed together to buy clean electricity.

The PPA was arranged by deal brokers at The Energy Consortium and Squeaky Clean Energy to fix the price of renewable electricity from a portfolio British windfarms for the next 10 years. Continue reading “Twenty UK universities have agreed £50m deal to buy renewable energy from British windfarms”

Renewable Energy has Space to Grow

By replacing fossil fuels with renewable energy, nations could achieve their emissions commitments without encroaching on vital natural land, according to researchers in the US.

Low-emission energy sources like wind and solar can have a larger geographical footprint than fossil-fuel plants of equivalent capacity. Even so, the renewable-energy potential of already developed land is more than enough to fulfill pledges made as part of the Paris Agreement and could satisfy the total energy demand projected for 2050, the analysis shows.

At the 21st Conference of the Parties (COP21) in Paris in 2015, 196 countries agreed to aim to limit warming to less than 2 °C above pre-industrial levels. The rapid cuts in greenhouse-gas emissions needed imply a large-scale shift away from fossil fuels. Renewable-energy schemes are not without environmental impact themselves, however, so it’s important to choose locations and generation techniques that cause the least possible harm.

A carbon-fiber kite tethered to a buoy floating in waters 220 meters (761 feet) deep took flight in a test to prove that the future of offshore wind power might fly through the air.

The kite, owned by the Alphabet Inc.-subsidiary Makani and backed by Royal Dutch Shell Plc, completed its first demonstration about 10 kilometers (6.2 miles) off the coast of Norway in the North Sea. Continue reading “Bloomberg: Flying Wind Turbines Make Their First Trip Offshore in Norway”

How Businesses Can Further the Development of Renewable Energy

The corporate world has multiple incentives for switching to more sustainable practices. Direct savings realized by business leaders include taking advantage of tax credits and deductions and lowered utility bills. Indirect savings often take the form of increased profits as public relations improve and the company customer base grows.

How Businesses Can Further the Development of Renewable Energy

In the past, certain technologies like wind and solar posed problems for industry leaders due to intermittent outages. However improvements in equipment and storage have made wind and solar power equivalent to the traditional grid in terms of performance and reliability. Here are the reasons to convert your organization to renewable energy and reap the financial rewards. Continue reading “How Businesses Can Further the Development of Renewable Energy”
