The price of photovoltaic panels has decrease by over 80% since 2010 and the cost keeps going down. Now the total cost of deployment is more affected by the availability of the surface and installation cost than the cost of the photovoltaic panel itself. Hence it shouldn’t be surprising that …

The Sun is bathing our planet with plenty of energy: some  173,000 TW are hitting our planet continuously, and to give a sense of how much that is, our total power consumption is less than 17 TW, 10,000 less than that. Actually, close to 40% of that energy  is reflected …

In yesterday  post I discussed the long term scenario of investment to reach, or at least aim at a net-zero carbon economy. The foreseen investment is huge, who is going to reap the (economic) benefits? Here the horizon is at the 2030, end of this decade. The graphic shows 11 …

The goal of reaching a zero impact in terms of greenhouse gas emission (CO2 and more) is in principle agreed by all, but when it comes to take action in implementing it “buts” and “maybe later” abound. An interesting web site to explore the variety of scenarios, their impact on …

We are chemical factories, our bodies is continuously engaged in metabolic processes and these produce heat (we are dissipating this heat through breathing and, unique in the animal world, through sweating). When we are packed in a closed environment we act like heeeating devices and the room temperature goes up. …

The quest for renewable energy is on and it will continue through this century as a way to decrease our dependence from fossil fuels, at least until fusion power will become a reality (and an affordable one, something that we cannot except in the first half of this century). We …

In spite of all the talking about becoming energy savvy, reducing our power consumption, humanity is bound towards increasing its energy dependence. The graphics included in the 2022 Global Energy Perspectives released by McKinsey shows this clearly. In 2050 it is expected a global use that is almost the double …

The growing usage of renewable sources makes it crucial the management of energy flow, both when there is plenty of it available and no corresponding demand (you want to store the excess production) and when there is no or little availability (no wind, non Sun, …) and the demand exceeds …

Beyond the tragic number of war victims the Russia-Ukraine confrontation is having a -growing- impact worldwide and for several European Countries a strong impact on energy sourcing. eas The ramification of energy shortage/increasing cost is broad, affecting industries, families and single individual. It goes even further impacting the climate on …

The Wright’s Law, also known as “Experience Curve” states that each percentage increase in cumulative production (production volume) results in a fixed percentage of production efficiency increase. Studies carried out at the MIT have found that Wright’s Law is a little bit more accurate than the Moore’s Law (doubling of …
