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

See previous BBC documentary on nuclear energy breakthrough

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.

I can't breath 🤢

DIGITAL ENERGY SERVICES as well as extensive services up to and including operation and maintenance services for PV power plants round off the SMART CONNECTED RANGE.

Renewable electric is beneficial to our climate.

Bla bla bla. Woke. Gay guys but most troubling
delusional.

Interesting. Burning wood waste (biomass) is considered renewable energy and lumped in with solar, wind, hydro and geothermal. Perhaps we need to talk more about emission-free energy since burning biomass puts CO2 and other combustion by-products directly into the atmosphere, rather than keeping it sequestered for decades in a forest that actually continuously captures CO2 & stores it? (Sure, trees eventually die and slowly release their stored carbon, but burning them is quick release and growing a new tree large enough to sequester the same amount of carbon as a mature tree takes decades.)

Calling wood burning renewable energy is technically correct but still undesirable for a variety of reasons. (Notice how smooth a politician is at dodging direct questions. It's a job requirement, apparently...)

Truth be told, it is almost impossible for us to reach our global temperature targets in time, and we might not even be able to slow the increases in GHG emissions from global economic development impacts significantly. Sure, governments will trumpet the increasing percentage of energy that comes from renewables, but they will avoid discussing the growing overall global demand for energy and the increased fossil fuel consumption that will meet much of that new demand.

The handwriting is on the wall, and all the greenwashing that sales & marketing and politicians can muster won't change the trajectory of global GHG emissions & global temperature increases. Doesn't mean we shouldn't deploy as much emission-free renewables as we can, but that shouldn't make us feel like the problem is being handled and we should just consume on without taking effective, quantifiable actions in our personal lifestyles.

Yes. It's far more lucrative to go with green energy, conservation, smart power upgrades, regenerative portfolios, and natural abundance.

The hydrogen economy is also a part of the campaign, standing alongside best practices, as well.

No one knows the future ok

Renewable Energy? Whahahahaha!

I need help

It is not a solution you are plugging gaps with another ff use fools

We really have to ponder this: why do the UK citizens pay a few times MORE than most people in the world when the renewables can now be even cheaper than energy from fossil fuels? To put it into perspective, in some Asian countries that only use natural gas to generate electricity, they pay only 10-12p per kwh (without standing charge) while we are paying bloody 27p per kwh + 35-40p standing charge per day! 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.

The battery is better and better. Electric motors is the best for the good of our mother earth.

Where is the dividing line betweenhuman caused and natural Climate Change. Without that knowledge all the crap being spread means absolutely nothing. If the speed linit is 80 mph you know the deviding line between a speeding ticket and getting home in time for dinner is at 80 mph
So when any of these climateers claim it's "HUMAN CAUSED" it means absolutely nothing because there is no indication of what and how much is natural causes.
Natural Causes like 1000's of undersea volcanoes or the increase of the population from 2.5 billion to 8 billion in just 60 years.
How is Lightning generated forest fire "Human Caused?"...These wannabe climateers don't have the sense of pocket lint. Without Carbon, we're all dead.......only an idiot can't understand that.
Not to mention there is no TECHNOLOGY available on earth that provide and average temperature. Earth has 200 million sq miles of are. 71% of that is ocean. Everything thats water, wind, gravity and sunlight are in constant motion every millisecond of time. When some one claims 1.5 inches of sea level change, it's a good bet they know nothing.
Temperture ...look at it with your own eyes on the weather channels. In one city it change from area to area by 8 or 10 degrees between breakfast and dinner. How can you possibly get an average of 1.5 degrees.
There is a serious mental absence here

Rely on Renewable Energy is Absolutely Yes! The other source of energy.

No the world cannot have renewable energy. Technically all energy we have access to is coming from the Sun. All this will end in few billion years from now and we all have to dig for another star 😅

Excellent review.

This is the BBC? Did I turn American overnight and nobody tell me?

Great video on renewable energy! I highly recommend the Segway Portable PowerStation Cube Series for outdoor enthusiasts like us. It has massive capacity, fast recharging, and versatile sockets. Plus, it's waterproof and has comprehensive protections. Check it out for reliable power during your camping trips or as a backup at home.

I am none the wiser as to whether the world can rely on renewable energy. Lot's of cool tech here but no real numbers on how scaleable they are 🤷

Of course. It is just a matter of time.

Regeneratives are available right now, and would greatly accelerate an all-sustainables global economy.

The build out of primary inputs will take some time. But, at some point renewables heavy energy production would be the norm.

The challenge of climate change and the energy transition is not the 'how' or the 'cost' but politics and nay sayers who fear change and are the target of lobby groups. Just think about this. It is cheaper to build a solar / wind with pv storage solution that generates the same amount of power than to run a equivalent capacity gas powerplant for 1 year. Think about it. How much you hate change, that is so absurdly cheap that even the most climate critical political party cannot ignore it. So what about intermittency in winter and at night? Easy we just build 7x the capacity of the fossil fuel counterparts. We would make that money back in 7 years! And the added bonus: if the wind is blowing and the sun is shining: energy will be near free. The biggest problem: What company would build so many renewables if you cant charge for it when they are generating the most? Companies will not do it, governments will need to do it. The energy transformation will shift the power from energy companies back to gouverments and the economy will be booming because power will be almost free.... The energy transition challenge is the people who are opposed to change. We need to convince people to accept the change and see the potential.

Great job,sealing old oil and gas wells 👌👍

Is any of this related to the title ? No it doesn't seem to be. Why not simply type a sting of nonsense as the title? Oops sorry, you have.

What does upstate New York mean ? State of New York rather than the city of New York? Upstate= in the mountains? or upstate= in the north of the state ?

For the metane emission, Dairy/beef industries should have been mention since they are the greatest emitors by far.

In October 2022 UN Under Secretary General for Global Communications Melissa Fleming speaking at the WEF event said that any search on Google always returned their data on climate change. She then stated that “we (the UN) own the science” So much for independent climate science?

Nice, but greenwash from the aviation industry. What needs to be said is 'we need to fly less' - but will an industry based on making profit from air transport ever say 'consume less to reduce the footprint'?

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!

Never fly, walk take public transport, phone, go online for conferences. There is no way for many-many decades to fly without destroying the planet. There is hope in the return of airships. Canceling methane is a hopeful move. I doubt if renewables can do the job by themselves. Modular nuclear is now cheaper and safer. fossil fuels kills 8.1 million people every year then hurricanes, wild fires, floods kills and uproots many more. Killing more indirectly by the loss of crops so by starvation. There is some greenwash in this programme. If we don't face the gravity and difficulties of the climate catastrophe honestly we will not solve it.

Millions of years ago dinosaurs farted methane that set the world on fire.

Delta is full of it. Greenwashing. They're not the only airline at this either.

No increase in hurricanes, tornadoes, wildfires, heatwaves, floods, droughts, climate migrants, sea levels, Polar melting, or species extinction, because of CO2, which a negligible amount is caused by humans. A huge increase in crops production, and the Earth greening, thanks to CO2......... there is no "Climate Crisis"........ I am not a bot with several subscribers and no content, I have a channel where I show my face!. There is no such thing as "Green Energy"

There is no climate emergency, CO2 is not causing warming of the planet. Go research the heat forcing properties of CO2, it’s a minor inefficient greenhouse gas. Stop swallowing what the media feeds you. Do your own research!!

Great video on renewable energy! As an outdoor enthusiast and RV lover, I highly recommend the Segway Portable PowerStation Cube Series. Its versatile design, massive capacity, and fast recharging make it perfect for extended outdoor adventures. Plus, its waterproof technology ensures it can handle any weather condition. Check it out!

Are there enough raw materials for renewables?

Just stop flying 🤷🏻‍♂️. Use zoom or take a train.

Unfortunately every watt of alleged green power has to be backed up with fossil fuel as if you don't you have power cuts as proven in the UK when it was tried. So not only do you have to manufacture the reusable equipment thay are actually increasing pollution as there's on way to guarantee power with out fossil fuel & we are burning fossil fuel & not using it just wasting it.
