Bung Bismo, Ini sedikit copy paste infos.
Mengenai costs itu saya kurang tahu berapa dollar per Megawatt atau teraWatt. Tetapi ini berita untuk tambah penglihata : GEOTHERMAL Where hot underground steam can be tapped and brought to the surface it may be used to generate electricity. Such geothermal sources have potential in certain parts of the world such as New Zealand, USA, Philippines and Italy. Some 8000 MWe of capacity is operating, including 3000 MWe in the USA and 2000 MWe in Philippines, and in 2002 geothermal produced more electricity than did wind worldwide. In Japan 500 MWe of capacity produces 0.3% of the country's electricity. In New Zealand 420 MWe produces over 7% of the electricity, and Iceland gets most of its electricity from 200 MWe of geothermal plant. Lihir Gold mine in Papua New Guinea has 56 MWe installed, the last 20 MWe costing US$ 40 million - about the same as annual savings from the expanded plant. Geothermal electric output is expected to triple by 2030. There are also prospects in certain other areas for hot fractured rock geothermal - pumping water underground to regions of the earth¹s crust which are very hot or using hot brine from these regions. The heat - around 250ºC - is due to high levels of radioactivity in the granites and because they are insulated at 4-5 km depth. They typically have 15-40 ppm uranium and/or thorium, but may be ten times this. The heat from radiogenic decay is used to make steam for electricity generation. South Australia has some very prospective areas. selain itu: http://www.evworld.com/article.cfm?archive=1&storyid=765&first=3858&end=3857 Cheap Electricity From Iceland By Dr. Pieter van Pelt A proposal to 'ship' renewably-generated electrical power from Iceland to Europe. ----- Original Message ----- From: BDG KUSUMO To: [email protected] Cc: [EMAIL PROTECTED] ; Koentyo ; [EMAIL PROTECTED] Sent: Monday, May 21, 2007 3:52 PM Subject: [nasional-list] Re: [mediacare] Fwd: [media-jateng] ANTI NUKLIR MULAI DISUARAKAN TERBUKA, BAGAIMANA DENGAN ANDA Bung Sunny, bagaimana yg di Iceland itu kalau costs nya dibandingkan dengan PLTN dengan kapasitas yg sama? Dikatakan alternatif2 terhadap PLTN sangat mahal, jadi konon PLTN bisa menjembati kurun waktu ketika sudah akan ada sumber alternatif yang costs nya memadai. Apa kawasan Gunung Muria di Jateng betul-betul sip (save) untuk lokalitas PLTN?

Lihat pada Island, panas bumi [urat magma] dijinakan untuk pembangkit tenaga listrik, tanpa perlu memikirkan bagaimana menyimpan sampah seperti pada tenaga nuklir [nuclear waste]. Mungkin diutamakan pemakaian tenaga nuklir karena enpelopn dibawah meja sangat tebal sekali. ----- Original Message ----- From: radityo djadjoeri To: [email protected] Sent: Monday, May 21, 2007 2:46 AM Subject: [mediacare] Fwd: [media-jateng] ANTI NUKLIR MULAI DISUARAKAN TERBUKA, BAGAIMANA DENGAN ANDA
