  • Over the past two years, energy prices have soared to record levels across Europe, leading to renewed efforts to harness renewable resources.
    Portugal has turned its sights to solar power - and the country is now home to Europe’s largest floating solar farm.
    Located on a reservoir in southern Portugal, the farm is the size of five football pitches and is made up of 12,000 photovoltaic panels.
    It generates enough energy to power 15,000 homes in the local area.

      There are positives and negatives to putting panels in fields and on hills or mountain sides. Aside from generating energy, the greatest positive is that they give added protection to certain wildlife by creating a new type of biome. The negative is they are a complete eyesore!

    I am not sure why there has to be one technology that's the "future" of clean energy. There are so many different techs which could lend themselves towards a solution, depending on location and need. Solar and wind, geothermal and wave, tidal and microhydro... they're all potentially viable.

      I think we'll have to intelligently utilize and overlap multiple methods everywhere to generate and consume energy wisely and safely. As it is, we're wasting time, resources, and opportunities by letting big oil, nuclear, and big money stalling tactics divide and distract us all. Consumer demand for reliable longer lasting renewables is growing, and our collective leverage grows with it.

    This seems to be en excellent combination. It completely eliminates the need for storage batteries to deal with the variable and intermittent nature of the panels output because the production from the dam can be easily adjusted to compensate. The solar panels output is 5 megawatts, which is less than one percent of the dams 518 megawatts, and even if the solar array is increased in size to the projected 75 megawatts the dams generating station will still be easily capable of compensating for the panels variable output. The panels will be more efficient because the water keeps them cooler, evaporation from the reservoir is reduced by the shading of the water, the cooler water and shade provided may prove surprisingly beneficial for aquatic life, and the individual panels can remain at a fixed angle with the entire array rotating to follow the sun.

      There are several ways to store solar energy. Once you turn it into electricity you can pump the water back up into the reservoir if you want. Not very efficient though. You can heat water and store hot water music for energy healing excetera. Solar energy can be stored in the ground in rocks and water tank. It's all unconventional at this point and it's all being tested, and it seems to be the definite path to save the environment of our planet.

    There is another downside as well. You want your panels to be about 30-40 degrees to the horizontal for maximum radiation in the UK ,depending on the season. Your revenue from the project is a factor of cos theta where theta is the mismatch in alignment. I suggest we go looking for a south facing hill of about 30-40 degrees. After all it would be too steep to grow crops on. You get more cash than sheep farming per acre.

    Not a new idea at all. Places with limited land like Japan have been doing it for ages. Obviously it isn't 'the future' but one way that solar panels will be installed. 'The future' is combined wind and solar in many different locations, as well as various other renewable sources such as hydro. For homes, the future is rooftop solar wherever possible as that reduces transmission requirements, but there will always be a need for some solar farms for industry and cities.

Most of my panels just stay that way. Some of them I can tilt. I'm boat it is definitely cheaper you sure to keep the refrigerator freezer going and lights and a couple of pumps.

      I should imagine that a solar panel is nothing more to marine life than a dark cloud (there will be some reflection and refraction around the edges and through gaps between panels). Since it floats it can be moved anyway, and marine life that can do the moving for itself will go and find a sunnier spot to swim if it wants.
      In addition, given how very hot last summer was in Europe, I wouldn't be surprised if that little extra shade wasn't a 'relief' rather than a hindrance to marine life.

      Wind and solar energy is definitely safer, cleaner and cheaper than fossil fuels. Regarding nuclear power, it is not so clear. There is a wide range of generation costs and co2 emissions per kwh of electricity when it comes to nuclear. An objective view is essential to finding the best way to move forward. We have to have an open mind about alternatives. Fossil fuels are destroying the environment and harming/killing plant and animal life. That is fact. Moving away from those destructive energy sources has top priority. And using solar and wind that are environmentally friendly is a good idea to lessen our negative impact on the world. But nuclear energy may also play an important role in our transition.

    This is correct.

    So one can say we burn fossil fuels for 100% of everything today and little will change over the coming decades.
    It is obvious that the quickest way to deal with this, is and cut down the use of fossil fuels is simply to cut down to use of motor vehicles.....But the opposite is happening as most people now work in cities and because the cost of living and housing in cities is growing exponentially as is the number of people living there, more and more people use more and more fossil fuels to travel back and forth to work as they live further and further away from the centres.
    The roads have never been busier.
    The use of all forms of transport using fossil fuels have never been higher and it will increase unless drastic action is taken,
    The demand for Energy (which uses fossil fuels) rises exponentially....
    In reality therfore, there is no action being taken by any governments other than encouraging the use of EVs which as we know is driven by money and profit and nothing else. (same with heat pumps, solar energy and wind turbines).
    If climate change is real, then there is nothing being done about it, other than seeing it as a way of making money and profit.....

    Interesting, I gather they would not block light into the ocean? If that's the case it would not effect sea life, or change currents in the ocean (if there is a large enough area to cool water underneath it). To say this is a better option is literally just the out of site out of mind type ideas. It would take more resources to repair, weather could effect them more drastically, and they would have to be tethered to something to not drift along sea currents.
    I'm not saying don't consider it, but don't please don't think that this idea is like better than other ideas. There are benefits, and drawbacks. Most of these will be unforeseen stuff regarding our ocean ecosystems. Is it clean energy if it say causes the coral to stop producing? Or change the migration of all sea life under it? Or cause current changes that effect regions of the planet in the worst case scenarios.
    Yes it is an option, but I think messing with the climate control for the planet might be in long term probably unwise? We are constantly placing new stuff in without actually testing the impact of things. Maybe we should test that and get some idea of what long term effects of this might be?
