What’s the most promising future energy source?
Switzerland has an ambitious strategy to achieve carbon neutrality within the next 30 years, which includes the further development of renewable energies.
We’d be interested to hear your thoughts on the potential benefits and drawbacks of renewable energies.
From the article Can solar panels on highways accelerate the supply of green energy?
From the article How a Swiss start-up wants to reinvent nuclear energy
Hello,
where can I find studies and official documentary analysis refer to these:
"according to the Federal Office of Energy, installing panels on existing roofs and facades could provide 67 TWh of photovoltaic energy per year, a figure well above the Swiss authorities' target of 34 TWh per year by 2050 (compared to 2.8 TWh produced in 2021)."

Thank you
Salve,
dove trovo studi e analisi documentali ufficiali fanno riferimento a queste:
"secondo l’Ufficio Federale dell’Energia, installare pannelli su tetti e facciate esistenti potrebbe fornire 67 TWh di energia fotovoltaica all’anno, cifra ben superiore all’obiettivo delle autorità svizzere, che intendono arrivare a 34 TWh l’anno entro il 2050 (a fronte dei 2,8 TWh prodotti nel 2021)."

Grazie per l'attenzione, le auguro una buona giornata!
Personally, I'm leaning towards more solar energy - we're all seeing that summers are getting longer and more days of sunshine these days, even Switzerland is starting to have dry summers every year, so why aren't we making more use of solar energy?
Personally, I'm an environmentally conscious person, but even more of a rational environmentalist. When I see so-called environmentalists with short brains opposing the installation of solar panels on highways, opposing the building of wind turbines on hills, opposing the continued development of nuclear energy ...... opposing ...... opposing... ...against ...... I really don't know where the energy industry should go in the future.
Let me give you an example from my neighborhood. The building I live in has tenants proposing to install solar panels on the roof, and the less educated, anti-5G, anti-new technology tenants who live on the top floor are adamantly opposed, saying they are afraid of radiation (I thought I heard wrong at first), so we must continue to use electricity produced from coal, natural gas & nuclear that we buy on the European market. Well, we are very green!
我个人倾向于更多使用太阳能——我们都看到，如今夏季越来越长，日照天数也越来越多，连瑞士每年都开始有干旱夏季，我们为何不更多利用太阳能呢？
就我本人而言，我是个注重环保的人，但更是个理性的环保主义者。当我看到大脑短路的所谓环保人士反对在高速公路上安装太阳能电池板、反对在山丘上造风能发电机、反对继续开发核能……反对……反对……反对……我真的不知道将来能源行业该何去何从。
举个我身边的例子。我住的这幢楼有住户提出在楼顶安装太阳能电池板，住顶楼的受教育程度不高、反5G、反新技术的住户坚决提出反对，说是怕辐射（我开始以为自己听错了），于是我们必须继续使用欧洲市场上买来的用煤炭、天然气与核生产的电能。嗯，我们非常环保！
I have not yet found one argument - among many - in favor of covering highways and other suitable traffic areas with translucent photovoltaics.
- It is well known that practically no electricity is generated by snow-covered panels. However, since large amounts of waste heat are generated by traffic, including air friction and tire heating, as well as power loss from internal combustion engines, a much faster thawing of the photovoltaic surfaces can be expected, and thus also improved electricity yields during the winter. Further known advantages are hardly necessary winter service, avoidance of road salt, therefore smaller cooling of the road profile and consequently smaller road damages. In summer, less heating of the road surface and less heat input into the vehicles due to shading, which in turn loads air-conditioning systems more sparingly and thus also saves energy.
For the financing, energy bonds are to be favored analogously to defense bonds for the assurance of a sufficient power supply with equal importance. Tackling the problem of electricity shortage with nuclear power plants is irresponsible as long as the problem of waste can hardly be expected to find a solution accepted by the population. In addition, with the major risk of having to evacuate areas with millions of people, a 100% safety can be expected.
Ein Argument nebst vielen - für die Ueberdachung der Autobahnen und anderen geeigneten Verkehsflächen mit transluzider Fotovoltaik fand ich bis jetzt noch nicht.
- Bei schneebedeckten Panels wird praktisch bekanntlich kein Strom erzeugt. Da nun aber grosse Mengen Abwärme durch den Verkehr erzeugt wird, auch Luftwiderstandsreibung und Pneuerwärmung spielen nebst Verlustleistung von Verbrennermotoren mit, kann mit einem viel rascheren Abtauen der Fotovoltaikflächen gerechnet werden und so auch Winters über mit verbesserten Stromerträgen. Weitere bekannte Vorteile sind kaum notwendiger Winterdienst, Vermeidung von Streusalz, deshalb geringere Abkühlung des Strassenprofils und folglich geringere Fahrbahnschäden. Im Sommer geringere Aufheizung des Strassenbelages und weniger Hitzeeintrag in die Fahrzeuge der Beschattung wegen, was wiederum Klimaanlagen sparsamer belastet und so auch Energie spart.
Für die Finanzierung sind analog Wehranleihen für die Sicherung einer genügenden Stromversorgung mit gleicher Wichtigkeit Energieanleihen zu favorisieren. Das Strommangelproblem mit Kernkraftwerken anzugehen ist solange unverantwortlich, als das Abfallproblem kaum eine in der Bevölkerung akzeptierte Lösung erwarten lässt. Dazu müsste bei dem Grossrisiko, allenfalls Gegenden mit Millionen Menschen evakuieren zu müssen eine 100%ige Sicherheit erwartet werden können.
Hello,
Sales of hybrid and electric cars are increasing rapidly. Electricity production will not be able to meet the demand without nuclear power plants. No other technique (wind turbines, solar panels, hydroelectricity....etc) will be sufficient. The Germans have understood and are returning to nuclear power. The demagogy of the Greens has fallen by the wayside.
Bonjour,
Les ventes de voitures hybrides et électriques sont en forte augmentation. La production d'électricité ne pourra pas satisfaire la demande sans les centrales nucléaires. Aucune autre technique (éoliennes, panneaux solaires, hydroélectrique....etc) ne sera suffisante. Les Allemands ont compris et reviennent à l'énergie nucléaire. La démagogie des Verts est tombée à l'eau.
I don't know if the problem is really related to energy. I think it's mostly related to overpopulation and housing density. In fact it is a problem of growth and as it has reached its limits it is about rethinking our way of life.
Je ne sais pas si le problème est vraiment lié à l'énergie. Je pense qu'il est surtout lié à la surpopulation et à la densité de l'habitat. En fait il s'agit d'un problème de croissance et comme elle a atteint ses limites il s'agit de repenser notre mode de vie.
As a premise, we will admit that the hydroelectric energy by dam and accumulation or run of the river is already exploited in an optimal way.
For Switzerland and Northern and Central Europe, geothermal energy, whether underground or underwater, is permanently reliable.
For equatorial and tropical regions, photovoltaic energy is the preferred option because the sun shines abundantly.
On the water, tidal energy by damming estuaries or by floating near the coast is constant.
Where the wind blows sufficiently, wind energy. Two problems are to be considered: the wear of the components and the impact on the landscape.
Thoughts of a doctor who loves Man and Nature.
En premisse, nous admettrons que l'énergie hydro-électrique par barrage et accumulation ou au fil de l'eau est déjà exploitée de manière optimale.
Pour la Suisse et l'Europe du Nord et Centrale, la géothermie, qu'elle soit sous-terraine ou sous-aquatique est fiable en permanence.
Pour les régions équatoriales ou tropicales, l'énergie photovoltaïque prime car le soleil rayonne en abondance.
Sur l'eau, l'énergie marémotrice par barrage des estuaires ou par flottement à proximité des côtes est constante.
Là ou le vent souffle suffisamment, l'énergie éolienne. Deux problèmes sont à considérer : l'usure des composantes et l'impact sur le paysage.
Pensées d'un médecin qui aime l'Homme et la Nature.
The development implies a closed cycle, i.e. in order not to have a shortage of energy it must be obtained from different sources, wind power plants, solar panels, dams and levees, hydrocarbons, decarbonization products and thus hydrogen in the future it will be possible to use SNF (nuclear fuel waste) recycling, what is the disadvantage. The drawback is that the industry is basically trying to focus on one source of renewable resources. And so the only drawback of the whole complex is the determination of the energy consumed.
Развитие предполагает использовать замыкающий цикл , то есть для того что бы не испытывать дефицит энергии её необходимо получать из разных источников , Ветреные электростанции, солнечные батареи , дамбы и плотины , углеводород, продукты декарбонизации а значит водород в будущем станет возможным использование вторичной переработки ОЯТ(Отходы Ядерного Топлива ) в чем же заключается недостаток . Недостаток в том что в основном промышленность пытается быть ориентированными на один источник возобновляемых ресурсов. И по этому единственным недостатком всего комплекса является определение потребляемой энергии
Wind and solar power are the cleanest ways to generate power. Nuclear is prone to accidents
Chernobyl and Fukoshima where reactors of generation 1. The nuclear industry is now focusing on generation 3.5 and heading towards generation 4. All future reactors will be extremely safe in comparison to the first generation and generally. Generation 1 reactors relied on sophisticated control systems which can of course fail, however modern reactors will rely on pure physics which will make them actually fail safe.
Even today after more then 60 years of nuclear reactors providing 10% of the global electricity, nuclear is statistically the safest and cleanest way of producing electrical power (even when taking Chernobyl and Fukoshima into account)).
The world is aiming at net zero emission of greenhouse gases by 2050, but we all forget to take into account that the world electricity consumption will at least triple by this time. There is no way Wind and Solar will be able to provide the required energy.
Modern society relies on a stable 24/7 supply of electricity. Only nuclear can provide this energy, and the sooner we adopt ourselves the better.
Hydrogen is produced from seawater to generate hydrogen power.
There is plenty of seawater available, and if it is used in hydrogen power generation, it will circulate as water.
There is little risk of a post-event situation like with nuclear power generation.
海水から水素を作り、水素発電をする。
海水はいくらでもあり、水素発電で利用すれば、水になるので循環する。
原子力発電のように事後が起きた時のリスクが少ない。
Current renewable energies have a too low energy yield. Switzerland needs to wake up from green fairy tales and start investing heavily in the only true energy alternative: nuclear.
Hydrogen is also good, but it requires water and used on a wide scale would cause huge water consumption issues. The same happened to biofuels. Great technology, butto power a car you need to use the same amount of farm land that can feed hundreds of people.
Nuclear power is the only real alternative to fossil fuels.
It is a political and cultural problem.
The logic of capitalism prioritizes economic benefits in an inequitable manner. This is obvious, but it is worth repeating. The global hegemonic system or the predominant establishment encourages consumption and the myth of the need for sustained growth, something unfeasible on a planet of finite resources. While we lie to ourselves thinking that science is the solution to everything, when in reality it is more part of the problem than the solution. It is like a beast that bites everything around it and then licks its wounds.
Es un problema político y cultural.
Las lógicas del capitalismo priman los beneficios económicos y en forma no equitativa. Es algo obvio, pero no esta de mas repetirlo. El sistema hegemónico global o el establecimiento predominante incentiva el consumo y el mito de la necesidad del crecimiento sostenido, algo inviable en un planeta de recursos finitos. Mientras nos mentimos pensando que la ciencia es la solución para todo, cuando en realidad es mas parte del problema que de la solución. Es como una fiera que muerde todo lo que lo rodea y después lambe las heridas.
The safest and cheapest energy is still solar energy.
However, solar energy cannot be used unless the sun is shining. It is also impossible to store energy when the climate is irregular, as it has been in recent years. On the other hand, oil and coal will increase CO2 emissions.
Nuclear power plants cannot cope with the consequences of accidents. I think that geothermal power generation, as Switzerland is promoting, and power generation by waves and wind in countries facing the sea would be a good idea.
一番安全で安価なエネルギーは、やはり太陽エネルギーだと思います。
しかし、太陽エネルギーは、太陽が出ていないと活用できません。近年の様に気候が不順だとエネルギーを貯めることもできません。かと言って石油や石炭では、CO2が増える。
原発では、事故が起こると対処しきれない。やはり、スイスが、推し進めている様な地熱発電や海に面している国では、波や風による発電等がいいのではないでしょうか。
Access to abundant and inexpensive energy will solve every world problem, save for the selfish heart of mankind.
Transportation, heating/cooling, agriculture, potable water, health and wellness.... Every sector of society can benefit from easier access to energy.
I am convinced that the source of this power is going to be nuclear. Of course there are concerns that need to be addressed and better practices and technologies developed, but if you are looking for energy that doesn't change the chemical make up of our atmosphere - nuclear will deliver.
My testimony of transfer to heat pump and all-electric: yes it is a big progress. Combined with mixed photovoltaic/thermal solar panels, the electricity bill is divided by two. Hot water is free for 6 to 8 months a year. No dependence on gas or oil.
And filling up the electric car in my garage costs 7 times less than filling up with gas.
- Cost savings
- Independence from fossil fuel imports
- No connection to the gas network, no tank or oil deliveries
- Clean, safe to use
- Environmentally friendly to a large extent (CO2 reduction well over 50%, including grey energy)
- Solidarity through the production of solar electric energy for the community
Mon témoignage de transfert vers la pompe à chaleur et le tout-électrique: oui c'est un gros progrès. Conjuguée avec des panneaux solaires mixtes photovoltaïques / thermiques, la facture d'électricité est divisée par deux. L'eau chaude est gratuite durant 6 à 8 mois par an. Aucune dépendance au gaz ou au mazout.
Et le plein de la voiture électrique dans mon garage coûte 7 fois moins cher que le plein d'essence.
- Economie
- Indépendance aux importations de combustibles fossiles
- Pas de raccordement au réseau de gaz, pas de citerne ni livraisons de mazout
- Propreté, sécurité d'emploi
- Ecologique dans une large mesure (réduction de CO2 largement au-dessus de 50%, énergie grise comprise)
- Solidarité par production d'énergie électrique solaire mise en réseau pour la communauté
The advantages of renewable energy are that it does not emit CO2 and can be used repeatedly.
Disadvantages are high cost and inability to provide large power
Many people want nuclear power, but
This is definitely a mistake
Uranium is more easily depleted than oil
Very few places where uranium can be extracted
Nuclear waste needs to be stored for 100,000 years
Human history is only tens of thousands of years old
The uranium that powers nuclear power plants will surely be depleted
Mankind will never be able to manage waste for 100,000 years.
Plutonium, the material for nuclear weapons, can only be made from nuclear power plants.
Eliminating nuclear power plants will inevitably lead to the elimination of nuclear weapons.
Switzerland should become a world leader in renewable energy.
Not only a neutral country militarily.
By becoming energy neutral
We should be a leader in peace.
One of the reasons for war is the struggle for energy
The world would be a more peaceful place if we no longer had to compete for energy.
再生可能エネルギーのメリットはCO2を出さない事、繰り返し利用できる事
デメリットは高コスト、大電力を用意できない
原子力発電を求める人は多いが
これは確実に間違い
ウランは石油よりも枯渇しやすい
ウランが採れる場所は極めて少ない
核のゴミは10万年保管が必要です
人類の歴史はまだ数万年しかありません
原発を動かすウランは確実に枯渇し
人類は絶対に10万年もゴミを管理出来ません
核兵器の材料のプルトニウムは原発からしか作れません
原発を無くせば必然的に核兵器も廃絶に向います
スイスは再生可能エネルギーの世界のリーダーになるべきです
軍事的な中立国だけでなく
エネルギー的にも中立国になることで
平和のリーダーになるべきでしょう
戦争の理由の1つにはエネルギーの争奪戦があります
エネルギーを奪い合うことが無くなれば世界はより平和になるはずです
solar
I think that energy saving and recycling are very important because resources are so limited
Ich denke, dass energiesparen und recycling sehr wichtig sind da die Ressourcen so begrenzt sind
Nuclear energy
Storing radiation waste for 1 million years or longer is a NO-GO! This decision could or should have been made 60 years ago. Instead of wasting money and resources with a NAGRA, Switzerland should have participated in breeder research. If the world wants it, by the end of this century it will be possible to order Generation X nuclear power plants from the catalog, which will recycle the existing nuclear waste, so that it will only have to be stored safely for a short time. Switzerland will have at least one of these nuclear power plants.
Wind power
Since Switzerland has no coasts for offshore wind farms, wind energy will be a marginal phenomenon. In the short term it will have to be expanded, in the longer term it will shrink again.
Solar energy
At the Heureka 1991 in Zurich I saw the almost zero energy house and wondered how to finance a grid that will one day only be used for peak demand. Solar energy will only become really useful when the storage of electrical energy achieves a miniaturization breakthrough, which will happen. Homeowners will then be able to supply themselves autonomously with electricity 7x24 and will avoid being connected to a grid as much as possible for cost reasons. Grid energy will mainly be used by business and public institutions. Two questions remain open for me: 1) Are there enough raw materials to cover the expected huge worldwide growth of solar energy? 2) What happens if at some point a volcano causes another year without summer? Volcanologists know it will happen! But it is also likely that no one will care until it happens somewhere.
Kernenergie
Strahlende Abfälle für 1 Million Jahre oder länger einlagern, ist ein NO-GO! Diesen Entscheid hätte man schon vor 60 Jahren treffen können bzw. sollen. Anstatt Geld und Ressourcen mit einer NAGRA verschwenden, hätte sich die Schweiz an der Brüter-Forschung beteiligen sollen. Wen die Welt es will, wird man bis zum Ende dieses Jahrhunderts AKWs der Generation X aus dem Katalog bestellen können, welche die vorhanden AKW-Wertstoffe verwerten, so dass sie nur noch kurze Zeit sicher verwahrt werden müssen. Die Schweiz wird über zumindest eines dieser Kernkraftwerke verfügen.
Windkraft
Da die Schweiz keine Küsten für Offshore Windparks hat, wird Windenergie eine Randerscheinung sein. Kurzfristig wird man sie ausbauen müssen, längerfristig wird sie wieder schrumpfen.
Solarenergie
An der Heureka 1991 in Zürich habe ich das Fast-Null-Energie-Haus gesehen und mich gefragt, wie man wohl ein Netz finanziert, dass dereinst nur noch für Bedarfsspitzen vorgesehen sein soll. Solarenergie wird erst dann richtig sinnvoll, wenn die Speicherung von elektrischer Energie einen Miniaturisierungs-Durchbruch erzielt, was geschehen wird. Hausbesitzer können sich dann 7x24 autonom mit Strom versorgen und werden es aus Kostengründen tunlichst vermeiden an einem Netz angeschlossen zu sein. Netzenergie wird hauptsächlich durch Wirtschaft und öffentliche Einrichtungen genutzt werden. Offen bleiben für mich zwei Fragen: 1) Gibt es genügend Rohstoffe um das erwartete riesige weltweite Wachstum der Solarenergie abdecken zu können? 2) Was passiert, wenn irgendwann ein Vulkan wieder einmal ein Jahr ohne Sommer verursacht? Vulkanologen wissen das es geschehen wird! Wahrscheinlich ist aber auch, dass sich niemand dafür interessiert, bevor es irgendwo eingetroffen ist.
One word: Hydrogen
