Researchers have demonstrated an innovative method for producing flexible solar cells from silicon (silicon) that are twenty-four percent more efficient than the cells known today and can still be rolled like a sheet of paper * The findings could allow the use of solar cells in applications that today use more expensive alternatives of thin surfaces.

If we don't change direction, these blackouts will only multiply

Opinion: The large power outage we experienced at the beginning of the month may be a preview of what is to come for the Israeli electricity sector with the increase in the frequency of heat waves due to the worsening of the climate crisis. The solutions are in our hands, now we just need to implement them, if we don't change direction, these power outages will only increase

A computational approach developed at the Technion will accelerate the integration of renewable energy sources into the electricity grid

Innovative methods of optimization, which make it possible to "smooth out" the fluctuations in renewable energy production by shifting the load in the network according to consumption. Said energy is stored during hours of low consumption, and when needed electric power is "injected" into the grid

According to the researchers, the main factor that predicts a consumer's willingness to install a solar panel is not his socio-economic status nor his political leanings - but the distance of his house from another house with solar panels.

The neighbor's roof is more solar

German and American researchers looked at what makes people install solar panels on their homes and found that if your neighbor has panels, it's likely that you will too. Does this logic also stand the test of the Israeli bureaucracy?
