Renewable Energy & Bioenergy Sectors
- 1. Biofuels （生物燃料，比如生物乙醇、生物燃油）
Liquid transportation fuels including biodiesel and bioethanol. These can be derived from a range of biomass sources, including sugar cane, rape seed (canola), soybean oil or cellulose. Our database excludes producers of base biomass, but includes suppliers of everything from the processing technologies and equipment, through the logistics of distribution, to manufacturers of energy systems which are specially adapted for the use of biofuels and products, and the services on which they depend. - 2. Biomass, solid waste and biogas （固体生物质、固体废弃物和沼气）
Production and consumption of solid and gaseous fuels derived from biomass. Solid biomass for the energy sector can include a number of specially-grown crops, such as elephant grass or coppiced willow, but it can also consist of crop residues such as straw. We include in this sector processors of other waste matter for energy generation, such as sewage waste, chemical by-products and biogas produced from municipal waste, as their exploitation often involves the same technologies as grown-for-purpose biomass. Increasingly we are seeing developers, generators and utilities enter this sector. - 3. Geothermal （地热）
Geothermal power has long played a part in the energy mix of countries with obvious geothermal resources, such as Iceland and Japan. Recent advances in two areas, however, mean that geothermal energy can play an increasing role worldwide: new drilling techniques allow users to tap into resources that had been too deep to access; and new ways of extracting useful power from lower temperature geothermal fields allow productive use of resources that could not have been used economically in the past. - 4. Mini-Hydro (<50MW) （小水电）
There may seem little new about hydroelectric power. Indeed at New Energy Finance we don't cover large-scale hydroelectric power projects. However, there are interesting developments in small-scale and low-head hydro power, and even very small scale hydro solutions. Hydro power is undergoing a renaissance and has a lot to contribute to the deployment of renewable energy globally. - 5. Marine （海洋潮汐能）
The marine sector covers all technologies relating to extraction of energy from the sea. Possibilities include waves and tide, either via tidal barrages or tidal flow generators. Note that exploitation of marine biomass would be categorised in biomass, rather than in this sector. - 6. Solar （太阳能）
The Solar sector covers all technologies that capture energy directly from the sun, either using a photo-voltaic (PV) material, or via a passive technology such as a concentrator or stirling engine. The solar energy sector is already substantial - cost reductions through new technologies or through increased manufacturing scale should see it breaking into new areas of energy demand over the coming decades. - 7. Wind （风能）
Wind is the renewable technology that has had the biggest impact on our energy usage patterns over the past decade. The next decade will see continued activity, particularly in developing countries and offshore. The Wind sector includes components and subassemblies for wind turbines as well as manufacturers of turbines themselves. A big part of this sector, however, consists of the various developers, generators, utilities and engineering firms that have sprung up to exploit opportunities to build wind farms around the world.
