To this end, the exchange with federal ministries as well as with members of the German Bundestag is sought. In addition, events are carried out as well as statements and expert opinions on concrete regulatory projects are drawn up and transmitted.

Dazu wird der Austausch mit Bundesministerien sowie mit Mitgliedern des Deutschen Bundestages gesucht. Zudem werden Veranstaltungen durchgeführt sowie Stellungnahmen und Gutachten zu konkreten Regelungsvorhaben erarbeitet und übermittelt.

Voltwise Power is a registered nonprofit in Germany. Donations to recognized charitable organizations (gemeinnuetzige Organisationen) are tax-deductible up to 20% of your total income. You will need a donation receipt (Zuwendungsbestaetigung) from the organization for your tax return.

You can verify Voltwise Power's charitable status in several ways. First, check the Zuwendungsempfaengerregister (ZER) at https://www.bzst.de/DE/Unternehmen/Zuwendungsempfaengerregister_organisation/zuwendungsempfaengerregister_organisation_node.html - the BZSt maintains this federal register of all organisations eligible to receive tax-deductible donations in Germany. Second, you can look up the association in the Vereinsregister (association register) at the local Amtsgericht (district court) via https://www.handelsregister.de/ - this confirms the legal form, registered address, and board members. Third, check whether the organisation holds the Freistellungsbescheid (tax-exemption notice) from its local Finanzamt - the notice is re-issued every three years and confirms the 'gemeinnuetzig' status under the Abgabenordnung. Legitimate charities publish this on their website or provide it on request.

Contact Voltwise Power directly for current donation methods. German charities typically accept SEPA bank transfer (Ueberweisung) to the organisation's IBAN, SEPA direct debit (Lastschrift/Einzugsermaechtigung) for recurring donations, PayPal, credit card payments, and online payment processors like Stripe or Mollie. Many German charities use platforms like betterplace.org, GoFundMe, or their own Spendenseite (donation page). International donors can give via SEPA transfer (Germany is in the eurozone) or PayPal. For your donation to be tax-deductible, you need a Zuwendungsbestaetigung (donation receipt) from the organisation - for amounts up to 300 euros, a bank statement showing the transfer is sufficient.

Voltwise Power is based in Oberhaching, in the Free State of Bavaria (Bayern) in southeastern Germany, the largest German state by area. Germany is a federation of 16 states (Bundeslaender). Charitable status ('Gemeinnuetzigkeit') is granted by the local Finanzamt and recognised nationwide - the organisation can solicit tax-deductible donations from donors anywhere in Germany.
