[obrolan-bandar] Mengapa batubara booming? Konversi energy (oil, coal, gas)
Berikut perbandingan perhitungan konversi energy (oil, coal, gas) (sumber dari BP.com) 1 barrel = 0,136 ton minyak mentah Kalau dibandingkan kalori yang dihasilkan 1 barrel minyak mentah = kurang lebih 0.2 ton batu bara kalori tinggi atau kurang lebih 0.4 ton batubara kalori rendah Jadi kalau 1 barrel crude oil = 90 USD, 1 ton coal = 100 USD ternyata masih murah banget ..

Yup, coal is the cheapest per mbtu, bahkan kalopun sampai oil tembus USD 120 Second cheapest is natural gas. Nafasnya masih panjang deh coal, kecuali Hillary Clinton/Barack Obama macem2.

Berharap juga Greenpeace n aktipis lingkungan dan Walhi (hihihi..biar terdengar dikit) tidak demo global warming ...krena Batubara merupakan bahan bakar yang super kotor Yang lumayan bersih natural gas ... Kalau Walhi mungkin demo-nya lebih ke pengrusakan hutan kali ya' ... Kayaknya kmaren juga pertemuan di Bali masih ogah tu US ngurangin emisi ... Kagak tau nanti klau new Presiden ...
