                              Major economies outside India Finally, India (90th) is facing a vast array of challenges in the power sector in order to meet its growth targets. Nevertheless, electrification appears to have progressed, with the proportion of the population covered having grown over the past six years by 4 percentage points to 79%. The need to become more energy-efficient, more diverse and less carbon-intensive is especially acute for major emerging economies, making it critical to progress with government responses to these pressures through energy reform. The following section assesses the countries that have significantly increased their EAPI scores as a consequence of policy decisions

                                          Major economies outside China The performance of China (94th) has been relatively stable, and is an example of how the scale of energy architecture can induce inertia in an environment of rapid change. The country now imports 12.7% of the energy consumed, compared to 8% in 2009. Overall, some good signals exist, such as the government’s efforts to curb pollution levels and the strong progress in providing access to energy. However, its sustainability metrics still lag behind many countries, with the share of non-fossil fuels decreasing by 2% since 2009.

                  Major economies outside Brazil  Brazil (25th) is the top performer among the BRIC nations ( Brazil, Russia, India and China ). It benefits from a diversified energy mix with a considerable share of low-carbon energy, and a growing domestic oil and gas sector providing revenues and reducing the need for energy imports. With its electricity supply dominated by hydropower, Brazil achieves a comparatively high score for environmental sustainability. However, its energy architecture is also deteriorating; shares of alternative and nuclear energy dropped by 6% in seven years, and the country has experienced a 10% increase in CO2 emissions from electricity generation over the same period. Its score for the quality of electricity supply also decreased in 2014-2015 compared to 2008-2009.

                   Major economies outside The  United Kingdom Similarly, the United Kingdom (16th) has ambitious policies to reduce its carbon footprint. The country had 12.4 GW of wind capacity at the end of 2014 (14), increasing the shares of alternative and nuclear energy in its mix from 13% in 2009 to 15% in 2013. The sub-indexes related to environmental sustainability and energy access and security both benefitted from this trend. The UK Green Investment Ban k, created and owned by the UK government, has been an important force backing green projects on commercial terms and mobilizing other private-sector capital in the country’s economy.

Germany (24th) decided to phase out nuclear energy production by 2022, and aims to reduce emissions by 80% by 2050. While the country has built impressive capabilities across the renewables value chain, the energy transition so far has come at a cost: the EAPI highlights sharp increases in electricity prices for industry, and German households, according to data in the index, pay the second-highest prices for electricity in Europe. As a result, the country dropped eight places in the ranking against the 2009 benchmark.

                                                                                       6. Climate Change                        Climate change, is yet another environmental problem that has surfaced in last couple of decades. It occurs due to rise in global warming which occurs due to increase in temperature of atmosphere by burning of fossil fuels and release of harmful gases by industries. Climate change has various harmful effects but not limited to melting of polar ice, change in seasons, occurrence of new diseases, frequent occurrence of floods and change in overall weather scenario. http://www.conserve-energy-future.com/15-current-environmental-problems.php
