Development in Offshore wind capacity Development in Offshore wind capacity
Offshore wind, currently around 3 000 MW, has mainly been concentrated in northern European countries, around the North Sea and the Baltic Sea. Europe’s leadership is primarily attributed to public policy and a thriving wind energy industry. EU legislation mandates significant reductions of carbon emission, requiring, among other measures, greater usage of renewable energy resources. As of 2011, around 69 wind farms were installed or under const...

Spots of potential for wave energy harvest Spots of potential for wave energy harvest
Wave energy is captured directly from surface waves or from pressure fluctuations below the ocean surface. Wave power varies considerably in different parts of the world, making it more economically feasible to harness in some parts than in others, hence making wave energy a region-specific energy source. For example, strong winds variations are observed within the band between 30 and 60 degrees latitude, and circumpolar storms near the southern...

Looking further offshore and in deeper waters Looking further offshore and in deeper waters
The high capital cost of offshore foundations bounds offshore wind energy to near shore locations. Most of the capacity has been installed in relatively shallow waters (under 20 m deep) no more than 20 km from the coast in order to minimize the extra costs of foundations and sea cables (EWEA, 2009). Most of the recently added capacity is installed in water depths of up 40 metres, as far as 60 kilometres off the coast, as shown in the figure.

Paper and paperboard production Paper and paperboard production
Though it is based on wood, a natural renewable resource, the pulp and paper industry is one of the worst sources of pollution. It absorbs more than 40 per cent of all timber felled worldwide. Despite the development of digital communications tools global paper production is expected to increase by 2.2 per cent a year from 330 million tonnes at present to 440 million tonnes worldwide by 2015. The main growth areas are Asia and Eastern Europe, but...

Traditional practices, infrastructure and development Traditional practices, infrastructure and development
Indigneous peoples have lived in Arctic for thousands of years, and continue to depend upon the natural resources of the region today. Their traditional subsistence practices include hunting, trapping, fishing and reindeer herding. All of which are conducted in a sustainable manner; that is, in a way that does not lead to long-term or large-scale degredation of the environment. However, the balance they have achieved with the environment through...
