Some US and Europeanwind power equipment manufacturers find the Chinese market so important that theyprefer to quietly follow the Chinese rules than complaining to their governments andresort to trade disputes. Many foreign companies circumvent the rules by setting upfactories and joint ventures in China. Gemesa, a leading wind power manufacturerfrom Spain, helped Chinese enterprises set up wind turbine component producingfacilities and its engineers trained the local component suppliers. The 70% localrequirements were dropped in 2009, by the time the localisation policy was sosuccessful that the local content rate of some of the foreign wind turbine producers’turbines sold in China had reached 95% and foreign producers began to supply theirmarket outside China with components supplied from China (New York Times, Jan30, 2010).IV. Renewable energy development – subsidies, job creation, andmanufacturing capacity building and technology competitiveness4.1 Renewable energy developmentIn the last few years, investments in various renewable energy have been growing atfast speed, especially solar PV, biofuel, and wind capacity have been increasingquickly. In 2010 (World Economic Forum, 2010), the global investments in solarpower and wind power grew by 49% and 31% respectively despite the economicdifficulties caused by the recent global economic and financial crisis. The worldinvestment in clean energy grew from the 186 billion USD in 2009 to 243 billion USDin 2010, for the first time approaching half of the 500 billion USD per year investmentindicated by the IPCC as necessary for peaking the global greenhouse gasemissions by 2020.Figure 4.

Source: REN 21, Renewables 2010 GlobalStatus ReportAccording to REN 21 (2010), by early 2010, more than 80 countries had enactedsome type of policy target and/or promotion policy related to renewable energy, upfrom 55 countries in early 2005. Renewable energy is increasingly seen as a greenindustry that will continue to grow rapidly in the coming decades and can bring aboutthe multiple benefits of climate change mitigation, local pollution reduction, reducingdependence on fossil fuel import, improving national energy security, as well asboosting economic growth and creating new jobs. In 2009, the total installed capacityof renewable energy (including only small hydro) reached 349 GW and electricitygenerated from renewable sources makes up 3% of the world electricity generation.renewable energy (excluding large hydro) contributes 3% of the global electricitygeneration,Despite continual cost decreases due to the fast growth in renewable energytechnology deployment and research and development, renewable energytechnologies except for large hydro, are still more expensive than fossil fuels.Levelized Cost of Electricity (LCOE) is the indicator for comparing the cost for eachkWh generation using different technologies over a power plant’s useful life.Table 7 is the IEA estimates of the Levelized Cost of Electricity (LCOE) costs of 6kinds of electricity generation technologies: nuclear, combined cycle gas turbine(CCGT), supercritical (SC) and ultra-supercritical (USC) coal power plants, coal with90% carbon capture (and storage) [C with 90% CC(S)], on-shore wind and solar PV.Competitiveness and job creation considerations in countries renewable energydevelopment plans. It can be seen that when the discount rate is 5%, it will cost moreto generate each kWh of power from wind and solar PV than the other four majorpower generation technologies. When the discount rate used is 10%, the gap is evenbigger (IEA, 2010).Table 7.
