以水电为主，地热、风能、太阳能等多能互补的新型能源体系全面建设。拉萨环网工程和输变电工程、青藏直流联网工程、川藏电网联网工程建成投入运行，结束了西藏电网孤网运行的历史；直孔电站、狮泉河电站、雪卡电站、羊八井地热电站、拉萨火力发电等应急电源项目建成发电，区内装机容量最大的水电项目藏木水电站发电，能源点建设加快推进。2014年全区电力装机规模达到169.7万千瓦，全年发电量32.2亿千瓦时。组织实施了那曲尼玛县、双湖县及阿里7县1镇无电地区电力建设项目，累计示范推广光伏系统3万套，建设光伏电站90座，太阳能路灯1200多盏，总装机容量8000千瓦。2012年底，实现行政村全部通电，基本解决无电人口用电问题。

　　以光缆、卫星、网络为主的现代通讯网络体系已逐步建立健全。现在的西藏已进入了卫星、光缆、网络、信息新时代。全区光缆线路长度达到9.7万公里，其中长途光缆线路为3万多公里，累计实现74个县、668个乡镇通光缆，乡镇通光缆率为97.8%；实现5261个行政村移动信号覆盖。全区互联网用户达到217.7万户，普及率为70.7%，农牧区移动互联网覆盖率达到65%以上。

An extensive energy system has now been formed with hydropower as the mainstay, backed up by geothermal, wind, and solar energy sources. Lhasa's Ethernet ring network project and power transmission and transformation project, the Qinghai-Tibet Power Grid Interconnection Project, and the Sichuan-Tibet Interconnection Project have officially gone into operation, so consigning to history the previously solitary operation of Tibet Autonomous Region power line. Such emergency power supply projects as Zhikong Hydropower Station, Shiquanhe Hydropower Station, Xueka Hydropower Station, Yangbajain Geothermal Power Station, and Lhasa's thermal power plant have been built and put into operation. Zam Hydropower Station, the hydroelectric project with the biggest installed capacity in the Region, has also become operational. Moreover, the building of energy bases was facilitated. In 2014 the total installed generating capacity reached 1.697 million kw, and the annual output of generated electricity came to 3.22 billion kwh. Tibet initiated and carried out power construction projects in Nyima County and Tsonyi in Nagchu, and in seven counties and one township in Ngari that were without electricity. The Region has demonstrated and promoted 30,000 photovoltaic (PV) systems, established 90 PV power plants, and more than 1,200 solar streetlamps, with a total installed capacity of 8,000 kw. By the end of 2012, all administrative villages had access to electricity, and the problem of electricity access had been basically solved.

Tibet has now entered the information age, having established a modern telecommunications network with optical cable satellites and the Internet as the backbone. The total length of optical cable lines in the Region has reached 97,000 km, among which over 30,000 km are long-distance optical cable lines. Optical cables have now reached 668 townships and towns in 74 counties, or 97.8 percent of all townships and towns in Tibet, and mobile phone signals cover 5,261 administrative villages. The number of Internet user households has reached 2.177 million, with an Internet penetration of 70.7 percent, and mobile Internet coverage in farming and pastoral areas has surpassed 65 percent.
