DC drives have been in use since decades. Oil and gas industry extensively uses DC motors and in the process DC drives. Other domains where Dc motor is required, its controlling DC drives have also been used. Crane and Trolley operations, belts and conveyers in industries, compressors and pumps have also been using it.

The verdict on biofuels is in and the catchphrase seems to be over-promised and under delivered. Biofuels have been in public use in some form or the other for a long time (Remember the Ford Model T that ran on hemp-derived fuel?). However, in reality, innovation in biofuels for widespread use is much more recent. First generation biofuels made out of sugar, starch and edible oils still occupy a major share of the total market. All the same, the biofuel industry has come a long way.

Customer microgrids or true microgrids are self-governed, and usually downstream of a single point of common coupling (PCC). They are particularly easy to imagine because they fit neatly into our current technology and regulatory structure. Hence, the market for these is expected to grow considerably over the next decade.

Virtual micro-grids cover Distributed Energy Resources at multiple sites but are coordinated such that they can be presented to the grid as a single controlled entity. Virtual grids are a developing field and the market is in a nascent stage. However, need for greater grid stability will drive the markets growth over the next decade.

Remote well site video monitoring, alerting, reporting services are cited to enhance well site safety, security and productivity. These services will play an essential part in oil and gas operations particularly in offshore fields, where access to the well site is limited and is located in harsher environments.

Global ‘Enhanced Oil Recovery Market’ is expected to increase at a CAGR of 20.4 percent from 2014 to 2020. Enhanced Oil Recovery (EOR), sometimes called tertiary recovery, is implemented to increase the output of an Oil field. Using EOR more than half of the oil can be extracted from reservoir, in some cases. Primary techniques employed in EOR are: thermal injection, gas injection, chemical injection and microbial injection.

The global hydropower market is expected to grow at a CAGR of 4.1% from 2014 to 2020. Hydropower is one of the oldest sources of energy which was used thousands of years ago - to turn paddle wheels that help grind grain. Hydropower is a versatile, sustainable technology and it is the world’s largest source of renewable energy and currently accounts for about 20% of the world's total electricity supply.

LNG is an attractive fuel choice for many shipping companies that are operating in the emission control areas (ECA’S), the LNG provides an attractive bunkering alternative because it exceeds the air quality standards and the price of the LNG is significantly lower compared to the Bunker Fuel. Although the use of LNG as a marine fuel is not a new concept, there exists a significant regulatory gap for the bunkering and associated infrastructure operations.

Global LNG infrastructure market, following a limited growth since 2011, the global nominal liquefaction capacity increased by over 10 MTPA in 2014 compared to 2013, with the start of liquefaction plants in Algeria and Australia. The present global nominal liquefaction capacity stood at 301.2 MTPA.

Global annual solar power production is estimated to reach 500GW by 2020, from 40.134 GW in 2014, making this market one of the fastest growing one. It is a billion dollar market with China leading the market of producing Photo voltaic cells. Germany is one of the leading countries for installing Photovoltaic across the country and has an installed capacity of 37 GW. It leads the pack with China, United States of America, Japan and Italy closely on its heels.
