Water, Sun, Wind, Biomass, Thermal, Wave and Ocean capacity are increasingly expanding their presence in the Energy Production global spectrum. Today they cover around 13% of total of Energy generation, and their fast increase is encouraging investments both from private companies and governments, supported by Climate Change and CO2 emission reduction policies.
Skills that CCL has been identifying and seconding to hydrocarbon projects for over 35 years are highly transferrable to the Renwables industry. Please contact us today to discuss our amazing catalogue of Engineers and Project Professionals.
In 2012, the world relied on renewable sources for around 13% of its total primary energy supply; in 2013 renewables accounted for almost 22% of global electricity generation, and this is forecast to reach 26% by 2020.
Hydropower is the biggest non-polluting source for electricity generation. An impressive trend is the growth in biogas, which was present in only 26 countries in 2000 and has now reached 63 countries worldwide. Part of the growth is due to conversion of existing facilities - the second unit at Drax power plant now produces energy from biomass. Lower production prices are a result of cheaper technologies and conversion of existing carbon production facilities into green energy ones.
Green energy capacity has increased 120% since 2000. Power capacity doubled over the last 14 years: from 800 GW in 2000 to 1.829 GW in 2014 and the positive outlook projects CO2 free energy production from the current 13% to 18% in 2040 (EIA outlook). In 2014 clean energy production grew by 0.6% on 2013 as a result of two main factors: increased investments in the sector due to ‘CO2 reduction plans’ and new technologies easing production processes, such as photovoltaic panels whose cost decreased substantially in the last ten years. Green energy, excluding large hydropower, employed 7.7mln workers in 2014 worldwide.
Natural cycles and dynamics of Sun, Wind, Water and Biomass help countries strengthen domestic self-sufficiency and increase export of fossil fuels.
China's increased investment in Renewables is leading the march, resulting in 26% of global hydropower production, three times as much as US (9%). The Red Dragon also holds the 31% record for wind energy, ahead of the United States (18%) and Germany (11%). Most notable are the Three Gorges Dam, a hydroelectric dam spanning the Yangtze River in Hubei province, China, the world's largest power station at 22,500 MW and the Jiuquan Wind Power Base in Gansu, China, potentially the world's biggest collective windfarm when completed in 2020.
Brazil is the world's second largest bioenergy producer, accounting for 13%, only a percentage point distance behind the US, and ahead of China in third with 10%. Philippines and Indonesia in 2014 had geothermal capacity of 16% and 11% of the global sector, dominated by US with 28%. Brazil is also the second largest global exporter of fuel ethanol (extracted from sugar cane), only surpassed in 2014 by the US. South Korea holds 48% of the global total wave and ocean capacity installed; second in line are France (45%) and Canada (4%).
In a future outlook Africa is expected to develop wind energy as an outcome of current massive international investment. Morocco is the land of international investments for wind power: Tarfaya onshore wind park with its 131 turbines is the biggest in Africa, operated by GDF Suex and Nareva Holding. Increasing demand for electricity in Kenya will soon be satisfied by the massive Lake Turkana Wind Power Project (LTWP); its 365 turbines will start working in 2016 with a capacity of 850 kW each and 300 MW total capacity.
Germany is the main country making the most of photovoltaic technology. In 2014 it produced 50% of global solar energy by generating 23GW; this also marked a double record covering half of its internal electricity consumption. Solar capacity installed is currently 38.2GW which amounts to 21% of the global total (179 Gigawatts in 2014). Its direct competitors are China and Japan with 16% and 13% of global capacity.
Strong winds in the North Sea make Denmark the largest producer of wind energy of Europe with 13TWh in 2014, satisfying 39% of domestic electricity demand. Denmark is also the main world’s exporter of wind turbines. British offshore and onshore Wind Mills are a fast growing sector powering a quarter of homes and filling 15% of the whole electricity production in the UK.
Most notable are the Anholt Offshore Wind Farm (AOWF), delivered by Siemens and owned by DONG Energy, generating 2,834GWh in 2014 and London Array, the world’s largest offshore wind farm, with 175 turbines 11 km off Kent’s coast generating 3,000GWh.
Hydro and wind plants are expected to push forward the whole Renewables sector: the average annual investment is set to $270 billion from now to 2040, 75% higher than the average registered between 2000 and 2013. In OECD countries, two-thirds of the investment in new power plants are set to go to green technologies.

Renewable energy comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat and account for 16% of global energy consumption (more than Nuclear), 10% being biomass, and 3.4% being hydroelectricity.
Hydroelectricity Fast Facts: hydroelectricity is produced by the falling and flowing of water and is the most widely used form of renewable energy, accounting for 16% of global electricity consumption, in 150 countries. China is the largest producer, with the Three Gorges Dam being one of the worlds 3 hydroelectricity plants larger than 10GW, the other two being the Itaipu Dam in Brazil and Guri Dam In Venezuela. Hydropower is a very cheap source of energy (once the dam is built) with no vulnerability to fuel price, and no carbon dioxide emissions; but dams attract a lot of criticism from their environmental impact. Norway produces 99% of its domestic electricity from hydro stations. The National Hydropower Association has 200 member companies.
Wind Power Fast Facts: wind is widely used in Europe, Asia and the US, with Denmark achieving 21% stationary electricity production, Portugal 18%, Spain 16%, Ireland 14% and Germany 9%, making it the second most successful renewable source, although it is more expensive per unit of electricity than fossil fuels. The tower-mounted three-blade turbines, typically tens of metres in diameter, are emission-free and quick to install, on-shore and off-shore.
Solar Power Fast Facts: Solar energy technologies include solar heating, solar photovoltaic, solar thermal electricity and solar architecture and the International Energy projects that solar power could provide a third of the global final energy demand after 2060, at very low CO2 emissions levels, with PV panels on house and business roofs becoming more and more common. But it is the most expensive form of renewable energy, so rarely economical except locally.
Geothermal Fast Facts: geothermal energy is used in 70 countries, mostly for heating, including piping hot water directly into buildings in Iceland. It uses the heat in the Earth's core, from rocks or water near the surface, or by drilling deep wells. But it only accounts for 0.4% of global generating capacity.
Boimass and Biofuels: whilst the predominant fuel until the beginning of the 19th Century, biofuels now has a small share. Biofuels are organic, non-fossil material of biological origin, such as plants, grain, sugar cane, vegetable oil, which can be converted into fuels, chemicals, materials and power. Even so, cars are produced that can run on a mix of fuels, including biofuel.
Marine and hyrokinetic (MHK) Energy - Fast Facts: MHK is a new renewable energy sector, involving wave energy, tidal turbines, in-stream turbines, ocean current turbines. Ocean Energy can also potentially generate electricity using the temperature difference between ocean water and surface water. Waves crashing onto shores add up to 2-3 million megawatts.
