A big problem a lot of people have with ‘alternative energy’ is that much of it is visually imposing.
Objections to a planning application for a solar farm near Ottery refer primarily to loss of farmland:

However, ‘good design’ might indeed be possible:
Celebrate change through design
Given the grim consequences of climate change and the political stakes associated with generating energy, the question of aesthetics may seem trivial. Investments in renewables obviously need to be based on more than just appearances.
However, as society quickly transitions to better sources of energy, designers are embracing the opportunity to reflect and celebrate the change. Seeing how big power plants, as well as hugely important small-scale community initiatives, can fit within the landscapes that people use and enjoy is a real challenge.
There will probably never be a power plant or solar panel that everyone deems beautiful. But debating beauty and design alongside function is vital to achieve better renewable energy developments.
