Remember the important geothermal locations in India:
\[
\boxed{
\begin{aligned}
\text{Puga Valley} &\rightarrow \text{Ladakh},
\text{Manikaran} &\rightarrow \text{Himachal Pradesh},
\text{Tattapani} &\rightarrow \text{Chhattisgarh},
\text{Vizhinjam} &\rightarrow \text{Kerala (Not Geothermal)}.
\end{aligned}
}
\]
Mnemonic: “PMT = Puga, Manikaran, Tattapani are geothermal.”
