Why It’s Too Soon To Let Renewable Energy Subsidies Expire

sunset with wind turbinesRenewable energy is starting to lose its subsidies because it has proved that it can be as cheap and even cheaper than fossil fuels. For example, China and the United Kingdom, two of the most ardent supporters of green energy, have recently pulled back on subsidies, and the Trump administration in the United States would also like to. But while wind and solar power rates can cost less than traditional fuels, the subsidies are masking another problem — one that is becoming apparent as the subsidies are eliminated.

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’”

Denmark’s renewable energy use passes landmark and is poised to grow in 2020s

Over half of Denmark’s energy in 2019 came from renewable sources, marking the first time the country has hit the 50 percent mark.

Figures from 2019 show the landmark use of renewable energy.

In 2018, the country took 43.5 percent of its energy from solar and wind power, while the figure for 2017 was just under 46 percent.

The data comes from state-owned company Energinet, which runs Denmark’s power grid. Continue reading “Denmark’s renewable energy use passes landmark and is poised to grow in 2020s”

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.

The benefits of renewable energy

Wind FarmSciTech Europa welcomes Steward McGrenary the director of Plunc, a high end electronics recycling company, to discuss the benefits of renewable energy.

Contrary to popular belief, renewable energy is not a new concept or recent fad. In fact, renewable energy has been successfully used for years, and has recently made impressive strides in technology, innovation, and efficiency.

However, as history would have it, the preferred method of energy use has always been the one that costs less upfront, as opposed to renewable energy, which keeps the environment cleaner and costs less in the long run. We are a society of immediacy. Continue reading “The benefits of renewable energy”

Apple partnering with tech giants for big clean energy buy

The wind farm, named the White Mesa Wind project, will be located in Crocket County, Texas. When completed in 2021, it will be capable of supplying 500 megawatts of power to the surrounding area.

Founded in 2009, Apex Clean Energy is a wind-energy company based in Virginia with 13 wind energy projects in Oklahoma, Texas, and Illinois.

Apple will be the largest purchaser in the agreement. Between the four companies, the purchase totals 75 megawatts of clean energy—or enough to power roughly 20,000 homes. The agreement will enable those involved to access cost-effective renewable energy from Apex. Continue reading “Apple partnering with tech giants for big clean energy buy”

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 Will Provide Discount to Thousands

“Poor families are going to receive hundreds and hundreds of dollars every year because of this. If we as human beings don’t think mother nature isn’t going to bite back because what we have done, then we are living in a false reality and we need to wake up. and this project is one way to wake us up and says there is a bright beautiful future that we can have,” said former congressman Joseph Kennedy II.
