Revolusi Tarif Tenaga Surya

POTSDAM – Revolusi sunyi sedang berjalan. Pada bulan November, Dubai mengumumkan  pembangunan solar energy park yang akan menghasilkan listrik dengan tarif kurang dari $0.06 per kilowat-jam– jauh mengalahkan biaya pilihan investasi alternatif, pembangkit listrik tenaga gas atau batubara.

Pembangkit ini – diharapkan beroperasi pada tahun 2017 – lagi-lagi menjadi pelopor masa depan dimana energi terbarukan mampu menyaingi bahan bakar fosil yang konvensional. Bahkan jarang sekali satu minggu berlalu tanpa pemberitaan tentang kesepakatan besar untuk membangun pembangkit listrik tenaga surya. Pada bulan Februari saja terdapat pengumuman proyek-proyek baru pembangkit listrik tenaga surya di Nigeria (1,000 megawat), Australia (2,000 MW), dan India (10,000 MW).

Tidak diragukan lagi perkembangan ini bagus untuk perjuangan melawan perubahan iklim. Namun pertimbangan utama yang menggerakkannya adalah keuntungan, bukan lingkungan hidup, sebab adanya peningkatan efisiensi dalam distribusi negara, dan apabila diperlukan, dalam penyimpanan, akan mengurangi biaya produksi energi terbarukan.

    Whither the Multilateral Trading System?

    The global economy today is dominated by three major players – China, the EU, and the US – with roughly equal trading volumes and limited incentive to fight for the rules-based global trading system. With cooperation unlikely, the world should prepare itself for the erosion of the World Trade Organization.

    The Globalization of Our Discontent

    Globalization, which was supposed to benefit developed and developing countries alike, is now reviled almost everywhere, as the political backlash in Europe and the US has shown. The challenge is to minimize the risk that the backlash will intensify, and that starts by understanding – and avoiding – past mistakes.

    A Better British Story

    Despite all of the doom and gloom over the United Kingdom's impending withdrawal from the European Union, key manufacturing indicators are at their highest levels in four years, and the mood for investment may be improving. While parts of the UK are certainly weakening economically, others may finally be overcoming longstanding challenges.
