Hi all and welcome to The Mad world of solar power in the United Kingdom. Now in the UK, you see plenty of small panels hooked up on slanted residential roofs. Panels installed in something path and at anything perspective, the homeowners’ roof happens to be. It’s close to just like the science of solar power is an afterthought and so I determined to make this video. The very first thing to assert is I’m no “what is the trouble with burning 90 million barrels of oil a day there is nothing flawed here” man or woman. I most likely think that renewable power is the future. However, that world force for renewables wishes to be balanced through the local realities for where you are and which renewables are essentially the most suitable and that’s what we’re going to speak about in this video. There are a lot of specific forms of renewable power solar, wind, tidal, biomass but what they all good except biomass have in usual is they may be able to simplest harvest the resources that are to be had within the first situation. If you haven’t any solar you can’t make sun vigor and so forth. I imply it can be very obvious when you’ll find the energy supply that you’re trying to make use of like in hydroelectric. You will see there’s a river, you will find you can construct a dam there and although you cannot see sun rays and also you can’t see the wind exactly the same stipulations apply to these too.
Nonetheless, it is perfectly feasible to measure the amount of on-hand assets of sunlight worldwide and here we see a map on that groundwork displaying world horizontal irradiation. It would be no surprise in the event you reside in the UK to listen to that it is not the sunniest nation out there however in comparison with the leisure of the sector it can be surprising just how “unsunny” it is. The United Kingdom receives around 2 to three kilowatt hours per square meter of sunlight energy that’s a few third not up to most of Europe where they obtain about 3 to 5 kilowatt-hours relying how South do you go and even Europe is particularly terrible in comparison with America where we see 4 all of the means up to 6 after we get in the direction of the desolate tract areas of the southwest. So you will see why there may also be very different incentives for specific international locations to have solar energy. In some places, there may be nearly thrice as much coming to the outside as there is in the United Kingdom and for that reason there’s way more to be had the power to harvest There are three phrases you’ll hear quite a bit when discussing electrical energy so I’m going to swiftly explain each time period.
First term “capacity” that is the instantaneous maximum quantity of vigor a device can supply like a one-kilowatt sunlight panel or a two-gigawatt energy station. Then “new release” the period of time on the whole stated in hours and share of capability used defines the exact amount of electrical energy generated, so it can be a combo of energy and time like a 1-kilowatt hour or 2-gigawatt hours. This is the precise amount of electrical power created and is the key number when you care about retaining lights on.
And sooner or later “capability aspect” this is the theoretical highest iteration in comparison with the actual generation you delivered, so you will see what proportion of the feasible capability used to be generated. That you can have tons of potential however if you can’t use it you’ve got terrible generation and a terrible capacity component So with that in intellect and this being show do not tell let’s take a seem at the genuine data for the UK. Here we have now mounted capability, that headline quantity for one of a kind forms of renewable energy and the area wherein they’re placed in the United Kingdom. You can find in England sunlight has nine and a half of gigawatts of mounted capability the largest single renewable contributor in England and politicians like to say this really somewhat. The UK overall is fairly more balanced in the direction of wind normally due to the fact that of Scottish wind farms the place they should not have a lot sunnier.
The other exciting number is biomass you will discover there’s best three-and-a-half in England however it’s very focused in the direction of York and Humber because there may be a single energy plant that is transformed to biomass and has around a two-gigawatt capability Now let’s seem on the actual meat-and-potatoes, the power new release from exceptional renewable sources. You will see the story is very, very distinct with the sun has been the biggest ability now some of the lowest contributors in England to renewable vigor at simply 8 and a half gigawatt hours out of the fifty-five which might be delivered. The wind is a way some distance ahead of sunlight regardless of having less capability. Actually, the wind has generated more than twice as so much and even biomass has generated much more. Correctly if we look at that one plant in Yorkshire and Humber its generated 50% extra energy than the whole solar industry in the UK so for all of that trumpeting of ability, the generation numbers are very very distinct. Now there are two most important objections that you would be able to make here initially the generation capacity customarily accelerated for the period of the year, therefore, this estimate can be somewhat on the low facet.
Secondly, this does not replicate the version for the duration of the year as to the specific electrical power generated. This paints a fascinating story, you can find there’s genuinely a number of one-of-a-kind cycles which can be going on in renewable energy in the course of the 12 months. Sunlight generates most of its vigor for the period of summer season nevertheless it’s definitely woeful for the period of wintry weather doing close to 5-percent potential. However, wind you will see suggests the reverse outcomes. It is customarily rather poor during the summer season and really very strong for the duration of winter. To place all this into point of view let’s seem at the story round Europe. Within the UK we’ve got on the IEA knowledge around a 10% capacity utilization. Southern Europe the place it can be most up to date you see 20 -15%, valuable Europe you see something like 12-thirteen % and in Northern Europe, you see even worse numbers than the United Kingdom, the Netherlands at around 8 and Denmark at around 9%. However, for me, the particularly exciting thing is how one-of-a-kind European international locations have spoken back to their occasions. The UK has round 40 percentage sunlight to 60 percent wind there are only some other countries that have the same or more and so they’re all landlocked primary European countries.
Even the southern European countries are likely to have extra wind and most likely everybody else who has an identical sun environment just like the Netherlands and Denmark have a way a long way extra wind than solar. It particularly raised the query “why is the UK such an outlier with regards to the energy mix, why is there a lot of solar rights here?” So what do our political leaders ought to say about this obstacle? “Mr. Speaker, will the Minister become a member of me in congratulating the UK solar energy industry for being one of the top 10 on the earth.
Better than Australia, rather smaller than Spain despite a rather less nice climate?” (Laughter) “indeed, had been it simplest the case the solar would at all times shine!” sure, if only we had a climber that virtually made this form of vigor priceless to us. If handiest? I imply who would have guessed? But finally all these renewables are paid for out of subsidies out of electrical energy fees that we pay in the United Kingdom, and the query I desired to understand then is “are we getting the excellent worth for renewable cash that we are paying?” and we can do that by way of assessing the amount of subsidy bought for every sort evaluate the number of iteration gigawatt-hours that have been delivered for each and every type of renewable energy.
Now here you will see that the answer. There may be two renewable techniques out there one is the renewable obligation and the 2nd is referred to as the feed-in tariff. The renewable responsibility has a breakdown for every type of energy, the feed-in tariff nevertheless does now not have a pound breakdown so we need to just pro-rata it between all the specific varieties and that gives us the numbers you see here. So once we add it together we find that for wind we paying a whole of round 2 billion pounds in subsidy in comparison with 850 million for sunlight. How much electricity did we generate for that money? Well, wind energy in 2015 delivered about terawatt hours of energy in comparison with sunlight which handiest delivered terawatt-hours and after we do the numbers the change is good no longer particularly no longer shocking given what now we have been speaking about for the prior 10 minutes. Wind vigor price around 49 kilos of subsidy for every megawatt hour it offers. Sun nevertheless charges 100 and 13 kilos for every megawatt hour it can provide. So let me put this an extra manner if we had taken that 850 million kilos from solar and used it for wind vigor we would have made more than double the amount of energy, an additional 10 terawatt-hours for no extra rate in any respect Now I stated at the begin of the video, that that is about nearby alternatively than world explanations and whereas provide is local so is demand.
Whenever we have now a mismatch between providing and demand we want storage. We store food during wintry weather that we harvested for the duration of summer and autumn and storage rate cash so an effective process we wish to fit deliver and demand and curb storage. Now a number of international locations on the planet have high sunlight intensity which we do not in the United Kingdom and the end result of that is it makes those areas scorching. People don’t find this comfortable in order that they want to cool themselves down. How do you do this? You utilize air-con. Air conditioning is a fridge however sized for a house and it runs utterly on electrical power. Now about three-quarters of yank properties have in-home air conditioning and in my existence in the United Kingdom, I’ve on no account once long gone to an apartment that had in dwelling air conditioning it just isn’t hot sufficient for it to be valuable. So what difference does that make to demand? Well, this is show do not tell so let’s simply have a appear on the numbers. So let’s appear at 2016 in the United Kingdom, electricity demand. You will see that that electrical energy demand is larger in the course of winter and it falls for the period of summer time after which rises once more as you head again into winter it types a u-shape.
Let’s appear on the information for America in the equal year. You’ll discover it starts out very equivalent, it drops as we go via spring but as we get to summer there is a big development in electrical energy demand due to air con, which then falls again once more towards the winter levels. Now if we put the 2 side-via-side we will see simply how significant the difference is. In the UK summer time has a 20% lower electrical power demand than winter and in the US the opposite is true summertime has a 20% larger demand and this takes us again to our seasonal capability factors.
You will see that why in the united states sun has price considering that that’s when it can be delivered and it would not need to be saved for the winter and that is why sunlight is sensible in the united states and other countries however makes no sense in the UK. I made this video since I believe in building a renewable energy future which we ought to be fascinated with developing. We are not able to treat this future as some political field-ticking predicament or as an undertaking to a peer who can set up extra sun billboards on humans’ residences.
It is not a global contest about who has most of 1 source of vigor. We must be clear on what we’re constructing and why we are building it. We ought to be clear on how the new energy infrastructure we are constructing leads us to the renewable energy future that we all want. It just isn’t past the capability of the UK to form a plan that is both regarded and being applied. Celebrating potential is meaningless, it’s particularly literally celebrating the potential to purchase gear.
In that Parliament clip, I showed earlier the UK was compared to Spain and Australia. Well, Spain has 20% much less established sunlight potential than the united kingdom but it generated eighty-three percent more energy given that of potential factors. Even doing the research needed to ask the query itself should have made it clear they had been deeper problems to be addressed. We need renewable new release, we ought to construct the infrastructure that our future relies on. Let’s focus on the technologies that in reality permit us to reap that future.
