It's most likely due to a rebate or cash back when changing providers. You can save a lot of money by switching providers every 12 months and taking cash back into account. If you have dispatchable loads (i.e. flexible charging of an e

Not exactly the same. Buildout of the grid in Germany lacks behind buildout of renewable capacity. Thus, when we have strong winds or a lot of sun, a lot of renewable production actually gets blocked at the source and/or the price of e

The tax reduction will almost certainly be extended and not be allowed to sunset. Industry electricity costs are more or less in line with other highly developed countries around the world and will remain so. Also, many larger industrial co

Civilized countries regulate the rates that lawyers can charge for standard work. Also lawyers get only reimbursed for reasonable costs by the loser. Still expensive, but not absurdly so.

My guess world be that the TSA had exactly nothing to do with any decline in hijackings. That is most likely due to new security protocols around cockpit access, as hijackings haven’t stopped but are committed mostly by pilots now. https:&

There is an official eu organic label. It’s not compulsory of course, but it’s the baseline for organic food production in and for Europe. Other (private) labels have stricter rules and are usually certified in addition to the EU label.
