Solar energy: Difference summer and winter
The teamwork of photovoltaic and biomass in a time where crude oil can no more keep up in the price as an energy source.
Photovoltaic delivers in Geramny In winter only 1/4 so much energy like in summer. We will reach once the point where during a sunny summer day almost the whole electric power comes from photovoltaic systems. However, also in this time the solar electric power production would be only a small part in winter time.
Biomass power stations could contribute in this time to the rest. However, biomass power stations are costly investments. Costly investments with low extent of utilization would raise the price of the power of biomass.
A solution is the fuel production. If enough electric power exists, the wooden gas is used in the diesel production if electric power is required, the wooden gas is processed in the gas engine to electric power and heat.
Even if one harvests in Austria, a land very rich in wood, about 10 million metric tons of wood per year more, there would be this scarcely 1 billion liters of diesel, 125 liters per inhabitant. 1,000 square kilometers of oil plants would still bring 100 million liters, again 12.5 liters per inhabitant. With it it becomes clear: for the today's mobility with 100% of internal combustion engines the biomass is by far not enough.
Most owners of electric cars have 2 cars. The electric car for all everyday journeys which are to be mastered with the modest reach of an electric car and a conventional car for all other journeys. A chargeable hybrid car combines both cars in one. All short everyday journeys with electric power, on longer journeys starts the combustion engine.
