Sustained interest

SOME are calling it a clean energy rush. The value of new investment in sustainable energy reached $148.4 billion in 2007, an increase of 60% from the year before. Investments have grown at around the same rate or higher since 2004, according to a study from the United Nations and New Energy Finance, a research firm. Those sums include investments by private-equity and venture-capital firms, money raised through stock offerings, corporate and government money for research and development, and investments in small-scale projects or companies building new renewable energy capacity. Wind-energy projects proved most popular with new investment of over $50 billion in 2007, followed by solar and biofuel.

A changing climate of opinion?

Some scientists think climate change needs a more radical approach. As well as trying to curb greenhouse-gas emissions, they have plans to re-engineer the Earth.

Green is good

Lower emissions often equate to greater efficiency-something the network infrastructure vendors are keen to point out to carriers looking to save money while growing their green credentials.
With as much as 86 per cent of an operator's carbon emissions coming from the power required to run its network, it should come as no surprise to find the infrastructure vendors promoting newer, more energy efficient solutions as a means of reducing not just the size of a carrier's carbon footprint, but also the size of its opex.
