Would Germany be possible with 100% solar electricity?
The expansion of wind energy is faltering. Is wind energy really indispensable for the energy transition or would it even work with exclusively 100% solar power?
How would 1400 GW of photovoltaics cope with 900 TWh of net electricity consumption in Germany?
| 00:00 | Start
| | 00:37 | Wind Energy Inventory and Expansion in Germany
| | 01:11 | Solar power alone? Question only made possible by new building standard
| | 01:41 | Distribution of world population by latitude
| | 01:53 | What is there on other continents at the latitudes of Germany?
| | 02:58 | Scenario 1400 GW photovoltaics 4000 GWh batteries 900 TWh consumption and power to gas
| | 06:10 | December 2020 lithium iron phosphate batteries for under 100 € / kWh total cost
| | 07:12 | Structure of the calculation
| | 08:41 | 80 GW CCGT power plants are enough, very few load changes
| | 09:45 | Extreme load changes every day in current system
| | 11:00 | Other design criteria for CCGT power plants - rapid load change becomes unnecessary
| | 11:53 | 180 GW power to methane is enough
| | 13:27 | Clear time separation between CCGT and power to methane deployment
| | 14:37 | A very sunny May week - 180 GW of Power to Methane all week
| | 16:27 | Evaluation of the result - 245 TWh of methane import needed
| | 18:16 | Level of underground methane storage
| | 19:16 | Surplus of southern countries for methane import needed
| | 20:11 | Expansion needs for underground gas storage
| | 20:35 | Hydrogen H2 unsuitable for power industry

| The heat pumps have arrived
|
| 
|
|
|
On December 16, 2020 paid, on January 27 the ship arrived in the Slovenian port of Koper. On February 19, the 3 heat pumps could be picked up at a forwarding agency near Salzburg.
|
| Rethinking cities
|
| 
|
|
|
The Green parliamentary group in the German Bundestag is hosting the online conference “Rethinking Cities” on March 19, 2021. We are participating in the virtual exhibition.
|
| The LiFePo4 batteries have arrived
|
| 
|
|
|
Ordered in mid-December, arrived on March 19. Low costs for electricity storage are a decisive factor for a real energy transition.
|
| Rethinking the energy transition: The price lie
|
| 
|
|
|
The demand for “more money for climate protection” is based on the price lie. But we need more motivation, credit and opportunity for a real effective energy transition.
|
| Summer / winter balancing of solar power — seasonal storage
|
| 
|
|
|
Different approaches to summer/winter balancing compared. Seven different locations, from Oslo to Cairo, are examined for seasonal balancing.
|
| Energy change — Food change — Social change
|
| 
|
|
|
Everyone is only talking about the energy transition for climate protection, but we also need a change in food production and in the social sphere. A solution for all 3 changes.
|
| Ventilation system with heat and moisture recovery
|
| 
|
|
|
On May 13, the last of the ordered units is ready for pickup at a forwarding company. The trip was nearly for nothing, because the device only barely fit through the tailgate.
|
| DIY test of thermal insulation of an alternative building material
|
| 
|
|
|
Construction wood prices are rising dramatically spring 2021 and there are supply problems. But wood prices for other applications, such as this material, are falling slightly.
|
| Ventilation systems with heat and moisture recovery
|
| 
|
|
|
Extremely economical and quiet, yet large power reserves to have the best indoor air quality even at a large party. Is of course part of the basic equipment.
|
| More efficiency in heating, cooling and hot water by 3 new patents
|
| 
|
|
|
How can you achieve a higher COP with an air-source heat pump than with a ground-source heat pump, and how can you drastically reduce the amount of electricity needed to heat water?
|
| Disruption at houses
|
| 
|
|
|
The market for homes is in as horrifying a state as the electric car market was in 2003: in the year Tesla was founded, the Peugeot 106 was a top electric car.
|
| A visual misunderstanding,
|
| 
|
|
|
or how a house shrank to 2/3 of its size. Because of this visual misunderstanding, the video “Disruption in Houses” was published again with improved graphics.
