Green energy Jobs

Howdy folks. I’m wanting to start a career shift into green energy. What does the industry need right now and what kind of mid level positions exist?

Interested in things other than door to door Solar Sales that would help grow the industry :)

Low cost silicon extraction for solar cells

Using a Fresnel lens or any other magnifying lens to heat silicon dioxide found in dirt/sand could reduce the energy demand for supplying pure silicon needed for solar and transistors. The heating is the most expensive part of the proccess since everything is so widely abundant and can easily be automated given current technologies allowing America and other nations to process dirt/sand to manufacture a nearly unlimited number of solar cells and circuit grade silicon given the abundance of silicon in the earths crust is 27.7% by mass.

To create the most durable and functional system under extreme offshore conditions. assumptions

assumptions

  • The equipment (infrared cameras, sensors) is resistant to saltwater corrosion.
  • The system continues to function properly even during severe weather conditions.
  • Temperature fluctuations in the ocean do not affect the accuracy of the readings.

quastions

  • How do sensors hold up in salty, high-pressure environments like the North Sea?
  • Can the system withstand storms or other extreme weather?
  • How do large temperature changes affect the performance of infrared cameras and sensors?

Recommendations for International Conferences and Journals for Publishing Research on Energy Systems Optimization

Hello everyone,

I am seeking your advice on some highly credible international conferences and journals where I can publish my research paper focused on optimizing the energy system of an entire country, with a particular emphasis on the implementation of renewable energy sources. Additionally, I prefer conferences with registration fees not exceeding 500 EUR.

If you have any suggestions or experiences in this area, I would greatly appreciate your assistance!

Thank you in advance!

To create an efficient real-time alert system that notifies windmill operators when an issue is detected.

assumptions

  • The real-time alert system can provide accurate and timely notifications to prevent serious damage.
  • The alerts provide clear, actionable information that windmill operators can quickly understand.
  • The system minimizes false alarms to prevent unnecessary windmill shutdowns.

quastions

  • How are real-time alerts typically integrated with offshore windmill systems?
  • How can false positives be minimized in a sensor-based system?
  • What factors affect the speed and reliability of alerts in offshore environments?

What's the Cost Comparison of Iron-Oxygen Energy Storage to Pumped Hydro?

I want to know how feasible Iron-Oxygen batteries will be since pumped hydro is not viable in my region due to cold temperatures. Using these iron-oxygen batteries with wind turbines may be cheaper than building nuclear reactors.

If there is any place to do nuclear, it is where I live in Saskatchewan since we have some of the lowest earthquake risks in the world. However, we plan to do SMRs, and I know a full-scale reactor will be ideal if wind and iron-oxygen batteries aren't feasible.

Please let me know what you think. Please share if you know of any other subreddit that may have an answer. Thanks!

Biogas is a regenerative storage technology. Why do we use it as a green baseload?

Germany has the largest share of biogas plants worldwide. Production is very flexible, and biogas is easily stored, making it the right technology to run on dark, windless days. Instead, evidence shows that it's run as a kind of green baseload. That contributes to

  • wind/solar potentially being disconnected from the grid during peak production conditions
  • less revenue for asset owners as they produce regardless of price developments

Interesting how subsidies have a way of freezing a business model even when market conditions have clearly changed. More here

Delta EcoFlow Inverter vs SRNE Hybrid Inverter

Help me decide on which back up system to get for my home. We are plagued by daily power outages and I’d like to get one of these systems installed asap but don't know which is best. Pros and cons?

I just heard the claim that all of Obama's green energy projects failed.

Please recommend sources which would discuss this claim.

AI sail boats for shipping

Hey Reddit,

Recently say a post about sailboats run completely by AI and was wondering if you had any thought on the idea of using small(er) cargo ship designs under wind power as a means of dealing with fossil fuel consumption.

With the recent turmoil at both the Suez and Panama canals the ability to move cargo around the globe has been backsliding. Traveling through the North-West passage is still unfeasible and not a great sign for climate change at that, but traveling south past Africa and South America while slower are feasible.

If AI cargo vessels where to come into common use it could provide cheap albeit slower means of transport. AI control mean no need for crew accommodations. Wind power means no need for fuel. Electricity for ship operations could be obtained from solar, wind, or regenerative propellers.

Not ideal for time sensitive cargo but for everything else? Is there some downside I'm not seeing? I've been pondering it all month and I'm not seeing any serious obstacles...though I have considered a few practical issues; piracy, disabled or damaged ship, cargo capacity, inclement weather, port navigation, sea obstacles (a la Titanic). Everything else I can think of boils down to maritime policy stuff.

Solar Energy Report Survey

Hey, I'm writing a report for my university course which needs us to make surveys for data collection so I'm posting here to get a wider data spread.

if you could take the time to fill it I would appreciate it 🙏

Survey Link: https://forms.gle/G4qddt6zW7ZHsecM9

Also, it would help if you've got feedback on the survey since this is my first one for a report.

Thank you!
