WORLDS PROBLEM?

Food ProductionTripled between 1950 -1985, since then it has leveled offAfrica, former Soviet Union and China seen biggest drops

1 in 6 do not get enough to meet nutritional needs

35% children deaths caused by malnutrition4

Indonesia tergolong negara yang sangat boros energi, dapat dilihat dari elastisitas energi yaitu perbandingan antara pertumbuhan konsumsi energi dengan pertumbuhan ekonomi, nilainya berada pada kisaran 1.84

Perbandingan Elastisitas Pemakaian Energi 1998 - 2003Sumber: Blue Print Pengelolaan Energi Nasional Departement ESDM, www.esdm.go.id grand energy growth meningkat 8% setiap tahunnya, dan pertumbuhan penduduk mencapai 1% per tahun, maka jika konsumsi bahan bakar cair tidak dikurangi, Indonesia akan mengimpor 1,5 juta barel crude oil setiap harinya pada tahun 2020
