Can the world rely on renewable energy? | Future Earth | BBC News

[@ResizeFilms]

The entire country of Portugal ran solely on renewable energy for six days in a row in November 2023. Portugal produced 1102 GWh of renewable energy from wind, hydropower and sun, surpassing its demand of 840 GWh, which allowed it to even export electricity to Spain. It’s a record. About 60% of Portugal’s energy comes from renewable sources today and is expected to run 100% on renewables before 2045.

Jean, grid supply needs a specific type of generator, renewables simply do not meet the requirements. They are a dead end and just make electricity more unreliable, more unstable and much more expensive. Hydro is the only renewable that does0 meet those criteria. You cannot go against the physical constraints and no amount of tecnical improvement of renewables will overcome their deficiencies. Persisting is s just ignoring reality.

What's weird people go nuts when oil companies want to drill anywhere near neighborhoods but developers build houses with working oil fields in them and in Firestone right over an working oil field with working under ground gas lines. Like, often these lines in old fields do not have allot of gas coming through them and this methane does not have a smell so cutting a pipe does not seem like a big deal. In the Firestone case the contractor simply cut the pipe and filled in the foundation hole. Again, no smell because it is pure methane so the relatively new house blew up killing a family.

Shame on BBC for spreading Delta Airlines' greenwashing. Global aviation represents 2.4% of global anthropogenic CO2 emissions, but roughly 3.7% of anthropogenic radiative forcing in 2018 came from aviation, and aviation emissions are growing 5% per year. Sostainable Aviation Fuel (SAF) is not a real solution. It may have net zero CO2 emissions, but Lee et al (2021) estimates that global aviation in 2018 had a radiative forcing of 100.9 mW/m2, of which 57.4 mW/m2 was from contrail cirrus clouds, 34.3 mW/m2 from CO2, 17.5 mW/m2 from NOx, 2.0 mW/m2 from stratospheric water and 0.94 from soot. In other words, SAF will only solve a third of the problem, but does nothing to address the other two thirds of the problem. Hydrogen planes are potentially worse than today's planes, because hydrogen planes will emit even more water vapor, leading to more contrails and more cirrus cloud formation, plus hydrogen tanks are high problematic from an engineering point of view. The only real solution is battery electric planes and VTOLs for short distance flights and airships and hybrid airplanes for long distance flights. Another option is switching more travel to electric high-speed trains or hyperloops. Hybrid airplanes can switch to their electric motors when passing through atmospheric conditions where cirrus cloud formation is likely. Until electric and hybrid planes are developed, the only solution is for planes to try to fly around areas in the atmosphere where cirrus cloud formation is likely, and the BBC should have asked Delta whether it would spend the extra money in fuel and incur the disruption of flight time schedules to do that. It was very poor journalism by the BBC to not understand the science and to not ask Delta the relevant questions, rather than letting the airline spew its greenwashing nonsense about SAFs. The methane from fossil fuel sources has a GWP-20 (global warming potential over 20 years) of 82.5 and a GWP-100 of 29.8 (IPCC AR6 WGI, 2021), meaning that 1 gram of methane has the same greenhouse warming effect as 82.5 grams of CO2 over 20 years or 29.8 grams of CO2 over 100 years. which is a lot more than "a greenhouse gas several times more potent than CO2", as this video said at 02:02. Since methane lasts an average of 12 years in the atmosphere (technically, its perturbation time), it has a higher impact in the short term.

[@bobbresnahan8397]

There is a difference between renewable energy and emission-free energy. Bio-fuel emits CO2 and other bad stuff. We need to transition to 100% emission-free, basically solar, wind, and batteries (SWB). When I got going in climate change, renewable sounded great. In fact, I founded a group called Renewable Taos. As time went on and we made local progress, we realized that we really need to focus on emission-free. That is the only proper focus to avert catastrophic climate change. It's a transition, so bio-fuels have some reason. But, they are actually very dirty. SWB is the actual solution. Cooking oil and ethanol are actually bad sources of energy.

[@ARLGD]

Thank you for sharing your knowledge about renewable energy. I completely agree with your focus on emission-free energy sources like solar, wind, and batteries.

Pity the latest figures say we've hit 1.54 this year having hit 1.5 for periods over earlier years. Most notable this year was the size of the jump, that the oceans around el nino don't look like they normally do which is to say instead of looking cooler they look hotter. The latest predictions pointout we're adding renewable on top of existing fossil fuel. Renewable is being used to meet new demand not replace old sources. The best predictions say 1.7 by 2030 and 2 degrees within 15 years or by 2038 and these maybe conservative as tipping points have been reached and the tipping we were warned of has occurred. The huge loss of albedo from missing ice means massive ocean warming. Boreal forests are converting themselves to tundra, temperate and tropical forests to grasslands in massive wildfires because we've taken too long. The roller coaster is moving and now natural processes will multiply the effects of the emissions we have failed to reduce. Climate zones are determined by latitude, altitude, topography and wind and ocean currents driven by temperature differentials. We've shifted those currents, slowed them and induced more, slower moving and larger oscillations in the jetstream. This means faster more severe, longer lasting droughts, longer cold snaps with heavier precipitation causing flooding and record snows. Our infrastructure built for one climate is going to face extremes and frequencies it wasn't designed for. Our crops and the biomes they evolved in will nolonger match the climates they are planted in. Fruit trees will set leaves instead of flowers due to warm winters, grain will rot in floods and prematurely die and dry off in heatwaves, continuing to push up world food prices, while leaving growing numbers hungry. Topsoil will be eroded in floods and blown away as dust at alarming rates. This bbc feel good is talking about the solutions to yesterdays problems, that were not able to be adequately implemented on time. The world has moved on and we need new solutions to adapt to the consequences of our failure to respond in time.

Having worked in the clean energy and renewables space for many years, I’ve seen a lot of misinformation touted in these interviews. Renewables are an intermittent source of energy. When comparing the price of renewables to other sources like baseload nuclear or fossil fuel energy generators, you need to look at the total system costs. These system costs include the transmission infrastructure needed to transport energy to consumers, and also the enormous amount of storage that’s needed when the renewables aren’t generating anything. If you include the cost of all this extra infrastructure, it is much higher than the cost consumers currently paid for their existing baseload generators. Moreover, the area footprint for renewable generation is much larger and conventional based generators. We need to ask ourselves where we’re going to get all the necessary minerals to realise these nets zero fantasies by governments where are we going to get a cobalt, nickel vanadium, silver?? There aren’t enough known reserves for these minerals at the present time? All these discussions about sustainable aviation, fuels are fanciful. Here, again. You need to look at the total system costs, which include harvesting all the biomass and organic resources, transport, costs and refining costs. How much landmass are we going to have to commit for these biomass fuels? And is that the most sustainable outcome for this biomass?

How could ours be that expensive? There must be something wrong with our system! Our government must fix this or everyone in the UK will continue to suffer badly, both socially and economically.

[@JetsG2020]

Renewables are more expensive when you take into account all the costs necessary to deliver a stable electricity supply (power lines to transport electricity from thousands of disparate solar and wind farms far from where the electricity is used, energy storage because renewables are intermittent and a stable electricity supply is needed, grid balancing to respond to changes in generation, the cost of maintaining stand -by natural gas power plants to cover renewables when they fall short, plus all the maintenance on the above plus all the interest cost on the vast amount of infrastructure that needs to be built to deliver all of this - much of the renewables were built with near zero interest rates). Also by inspection we know it is more expensive because if it were the cheapest it would not need subsidy and the UK would have high energy industries setting up on its east coast to take advantage or the wind energy from the north sea.. but in reality renewables are given subsidies, gas power stations are taxed, and high Energy industry is leaving the UK. So when someone says renewables are cheapest they are ignorant or gaslighting. Hopefully there will be more technologies that emerge that are more practicable than current wind and solar.

[@OldScientist]

The Royal Society recommend the UK should have 100TWh of energy storage (it's currently 39.3 GWh from 4 pumped storage facilities). That's over a 2,500 fold increase. That means building 10,000 pumped storage facilities or 400 every year. A typical pumped storage facility has a 300 to 400m dam built to hold back 10 million cubic metres of water, with a fall to the turbines below of about 400 metres. That's at the same time as increasing wind power generation from 75TWh (in 2020) to 665TWh (in 2050 - these are UK National Grid figures). That's around 100,000 giant wind turbines. And by the time you get to 2050, the 4,000 wind turbines you needed to install in 2025 would have reached the end of their working lives and will need to be buried in landfill, and replaced with another 4,000. It's all impossible and absurd. The cabling and additional structures to connect all this together will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the less than 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the whole Earth going Net Zero. Good luck with that.

If 100 countries say... "but we are only 1%" and do nothing, then nothing will change.

Saya sendiri juga masih bingung hidrogen liquid yang digasilkan oleh industri itu hasil pemisahan dari molekul air atau dari mana. Tapi itu erat kaitannya dengan air yang bisa d kategorikan sebagai sumber hidrogen dan oksigenkaly bagaimaña syarat dua melekul itu berhasil di pecah masih menjadi penelitian yang mesti kita pertanyakan bagaimana itu bisa

The new tech can make a difference if power generation is a human right and we can let middle and lower incomes pool their money together and fund a windmill or something literally giving the power to the people.

Mrs Richards: "I paid for a room with a view !" Basil: (pointing to the lovely view) "That is Torquay, Madam ." Mrs Richards: "It's not good enough!" Basil: "May I ask what you were expecting to see out of a Torquay hotel bedroom window ? Sydney Opera House, perhaps? the Hanging Gardens of Babylon? Herds of wildebeest sweeping majestically past?..." Mrs Richards: "Don't be silly! I expect to be able to see the sea!" Basil: "You can see the sea, it's over there between the land and the sky." Mrs Richards: "I'm not satisfied. But I shall stay. But I expect a reduction." Basil: "Why?! Because Krakatoa's not erupting at the moment ?"

Good Morning, Energy Star Good morning, bright Energy Star, You rise with power, near and far. Awake the day, your light so clear, Fueling dreams, chasing fear. Your beams ignite the endless sky, With warmth that makes the spirits fly. Each spark you give, we come alive, On currents bold, we dare to thrive. The fields you touch begin to glow, With winds that whisper, rivers flow. In solar streams and waves of air, You light the path, beyond compare. We greet you now with open heart, A shining guide, a brand-new start. Good morning, Star, let’s chase the flame, Together we’ll ignite the name.

When did the interview at the 8 minute mark happen? He says we have 8 years for "tripling." We have only 6 years. 6 years from today is 11/21/2029. This ambition seems unrealistic when countries are unwilling to spend their trillions on green energy.

Huge parts of Brazil and Paraguay rely only on hydro electricity since decades, congrats Vermont to joining the club, but claiming to be a pioneer is laughable.

Pretty much a dumb question. For 4.1 billion years renewable energy was the only form on energy.

[@roinretrospect]

Looking forward to seeing how the nuclear industry returns in strength with small modular reactors. I'm also happy to see Airbus developing hydrogen powered airplanes. We can produce the hydrogen for free from nuclear power plants!

[@zaurenstoates7306]

It's a bit of a half truth that renewables are cheaper than conventional alternatives. Yeah it's cheaper, if you don't include the necessary storage, transmission and nation wide interconnectivity needed to reduce storage needs. It's akin to me selling you the cheapest house on the market, but failing to disclose it still needs a roof and foundation

[@ralpharmsby8040]

Renewables will be proving power long after all available non-renewable fossil fuels and even uranium are mined out.

[@farber2]

How do we run farm tractors, not with solar or wind power.

[@farber2]

@josemercado3063 Feed 8 billion people that way?

Hydrogen. Biofuel. Even batteries.

[@farber2]

@@lilbaz8732 We are going to feed 8 billion people with hydrogen powered farm tractors?

[@ralpharmsby8040]

Some are powered by methane derived from farm animal waste but that's going to happen everywhere. Maybe fuel cells but they still need electric motors. There are already some huge electric articulated lorries so maybe there will be some big electric tractors soon.

Sorry the town of 50k people 100% renewables but burning 25% doesn’t make it 100%. A city in Australia has over 1.5 million population running 80-100% and exporting is something you should have reported on.

[@VK4VO]

Thats BS too, Adelaide has a massive interconnector from Vic which is a coal feed. Turn that off and sure theres your 100% renewable but a huge shortage of supply due to the required grid size demand. Thousands without power due to blackouts as whats happened in the past.

Mirror concentrators are not as cost effective as solar panels

[@grindupBaker]

Because it's new technology, too custom. Needs economies of scale, production-line manufacturing.

[@lilbaz8732]

It can store for 8 hours. So are solar panels with energy storage still cheaper?

[@voranartsirisubsoontorn]

Isn’t better to have alternatives?

The real question is can we rely on fossil fuels provided by the likes of nice guys like Putin and MBS

Still waiting for the space-based solar panel technology

[@davestagner]

By the time we get that, ground-based solar will have already won.

[@containedhurricane]

@@davestagner Ground-based solar panels take too much space and aren't as effective as the space-based one

[@davestagner]

@@containedhurricane How much space do ground receivers for space-based solar take? But seriously, “too much space” isn’t a defensible argument. There’s plenty of rooftops and parking lots, in addition to wide open spaces. Ultimately, though, it’d take 20 years to get space-based solar working at meaningful scale, IF we started now with an all-in effort. Ground-based solar is doubling every 2-3 years, in large part because you don’t need billions of dollars and tremendous engineering efforts and international cooperation to put up a solar panel. I do not understand the obsession with doing the most technologically difficult and ridiculously expensive approaches to getting rid of fossil fuels, when something simple and cheap is right there in front of our noses.

[@containedhurricane]

@@davestagner I bet it will require the space of a desert to match the power gained from a few space-based solar panels. If the space-based ones weren't potentially more lucrative in the long run, the UK scientists wouldn't plan to make them

[@davestagner]

@@containedhurricane Has a government invested at least a billion dollars into the idea? Is there a timeline? Could they have it in production by 2030? If the answer to any of these is “no”, then it’s going to have a very difficult time. The problem with all of these super-high-tech, incredibly complex solutions that have never been tried before is lead time. Ground-based solar is happening NOW, and costs are becoming very predictable - more predictable than another fossil fuel plant. It’s also the cheapest source of energy today, and battery costs are scaling and dropping to match. If it takes just ten years to get space-based solar started - and that’s aggressive - ground-based solar will have more or less wiped out coal and a lot of natural gas by then, on cost alone. At which point, what does space solar have to offer, other than cost, complexity, and massive risk?
