Fraking is really bad for all of us, it’s the process of using water to force dirty oil out of the ground. This practice destabilizes the ground causing earthquakes and the end result is more wasteful oil ultimately being consumed, which in turn, produces waste that gets released into the atmosphere. There’s nothing good about fraking. Scotland banned fraking in its territory last month and now it looks like the United Kingdom as a whole is on track to ban it too. With any luck the country will divert subsidies to the finite petroleum industry to the infinite renewable energy sector.
Environmentalists argue that the process contaminates water supplies, hurts wildlife, causes earthquakes and contributes to global climate change.
It is banned in many countries, including France and Germany, and the United Kingdom’s other constituent members — Scotland, Wales and Northern Ireland — are opposed to it.
Public mistrust of shale gas extraction is rising sharply.
According to the National Audit Office, opposition among Britons has risen to 40 percent from 21 percent since 2013.
“Public concern has centred on the risks to the environment and public health, from fracking-induced earthquakes, and the adequacy of the environmental regulations in place,” it said.
Oil and gas companies have seen the writing on the wall about the future of energy: it’s all about renewables. The Norwegian state-owned company Statoil installed a massive wind farm off the coast of Scotland and it’s a roaring success. The wind turbines float in the water and are operating more efficiently than their land-based counterparts. What’s more is that they survived hurricane force winds.
Hywind in particular was built much like a floating offshore oil drilling rig, with the platform anchored down to the seabed using suction anchors. These eliminate the need to construct expensive fixed structures under water and allow Statoil and others to site the turbines farther out to sea in deeper waters. Hywind specifically is 15.5 miles out from Aberdeenshire, Scotland. At maximum capacity, it can power 20,000 homes.
Despite its “floating” moniker, Hywind is well-equipped to withstand violent storms without capsizing. The system performed as expected during the extreme storms that hit it over the winter. In October, the proximity of Hurricane Ophelia exposed Hywind to wind speeds of 125km/h (80mph), and, later in December, another storm delivered “gusts in excess of 160km/h (100mph) and waves in excess of 8.2m (27ft).”
Portugal reached a very significant milestone on its path to being fully powered by renewables by consuming energy only from sustainable resources for four days. Other countries are on similar paths. In 2012 Germany got 50% of it’s power from renewable sources, Scotland powered itself exclusively on renewables for a week earlier this year, but the most impressive is Costa Rica. In 2015 Costa Rica went at least of a quarter of the using only renewables and improving this year.
Portugal joins those countries (and others) that are looking forward to a future that isn’t dependent on finite energy sources. More countries should be joining this renewable revolution.
Electricity consumption in the country was fully covered by solar, wind and hydro power in an extraordinary 107-hour run that lasted from 6.45am on Saturday 7 May until 5.45pm the following Wednesday, the analysis says.
News of the zero emissions landmark comes just days after Germany announced that clean energy had powered almost all its electricity needs on Sunday 15 May, with power prices turning negative at several times in the day – effectively paying consumers to use it.
Thanks to Delaney!
This past weekend Scotland generated enough electricity from wind turbines to meet all its power demands. A day of strong winds and low demand combined to make this the first time Scotland has achieved this renewable milestone. For a compression, in 2012 Germany got 50% of it’s electricity from renewable sources, and today Germany gets almost all of its power from renewable sources on a regular basis. In a couple years Scotland could be 100% powered by renewables. The cost of solar and wind installations continues to fall so it’s likely more regions of the world will be able to follow Scotland’s lead.
“It should also be remembered that wind power is not the only renewable power source Scotland has at its disposal.
“If we continue to take steps to reduce our energy demand, invest in storage, and increase our use of renewables we can hopefully look forward to many days that are fully powered by nature.”
The figures showed that wind turbines in Scotland provided 39,545 megawatts per hour (MWh) of electricity to the National Grid for 24 hours on Sunday. Scotland’s total electricity consumption for that day was 37,202MWh. It is unclear whether demand at any single point in the day exceeded the amount supplied by the turbines.
Tidal wave energy installations are nothing new, but installing it on a scale that can power 42,000 homes is. The other day, the Scottish government gave the go ahead for starting a wave-powered energy installation.
“This is a major step forward for Scotland’s marine renewable energy industry. When fully operational, the 86 megawatt array could generate enough electricity to power the equivalent of 42,000 homes – around 40% of homes in the Highlands. This … is just the first phase for a site that could eventually yield up to 398 megawatts.”
Speaking at the Scottish renewables marine conference, Ewing also announced that developers Aquamarine Power Limited and Pelamis Wave Power are to share a slice of a £13m wave “first array” support programme, part of the Scottish government’s marine renewables commercialisation fund.
Ewing said the tide is turning for the wave sector.
