Energy development is the field of activities focused on obtaining sources of energy from natural resources. These activities include production of renewable, nuclear, and fossil fuel derived sources of energy, and for the recovery and reuse of energy that would otherwise be wasted. Energy conservation and efficiency measures reduce the demand for energy development, and can have benefits to society with improvements to environmental issues.
Rural electrification is the process of bringing electrical power to rural and remote areas. Rural communities are suffering from colossal market failures as the national grids fall short of their demand for electricity. As of 2017, over 1 billion people worldwide lack household electric power – 14% of the global population. Electrification typically begins in cities and towns and gradually extends to rural areas, however, this process often runs into obstacles in developing nations. Expanding the national grid is expensive and countries consistently lack the capital to grow their current infrastructure. Additionally, amortizing capital costs to reduce the unit cost of each hook-up is harder to do in lightly populated areas. If countries are able to overcome these obstacles and reach nationwide electrification, rural communities will be able to reap considerable amounts of economic and social development.
The energy policy of Australia is subject to the regulatory and fiscal influence of all three levels of government in Australia, although only the State and Federal levels determine policy for primary industries such as coal. Federal policies for energy in Australia continue to support the coal mining and natural gas industries through subsidies for fossil fuel use and production. Australia is the 10th most coal-dependent country in the world. Coal and natural gas, along with oil-based products, are currently the primary sources of Australian energy usage and the coal industry produces over 30% of Australia's total greenhouse gas emissions. In 2018 Australia was the 8th highest emitter of greenhouse gases per capita in the world.
Renewable energy commercialization involves the deployment of three generations of renewable energy technologies dating back more than 100 years. First-generation technologies, which are already mature and economically competitive, include biomass, hydroelectricity, geothermal power and heat. Second-generation technologies are market-ready and are being deployed at the present time; they include solar heating, photovoltaics, wind power, solar thermal power stations, and modern forms of bioenergy. Third-generation technologies require continued R&D efforts in order to make large contributions on a global scale and include advanced biomass gasification, hot-dry-rock geothermal power, and ocean energy. As of 2012, renewable energy accounts for about half of new nameplate electrical capacity installed and costs are continuing to fall.
The China Township Electrification Program was a scheme to provide renewable electricity to 1.3 million people in 1,000 townships in the Chinese provinces of Gansu, Hunan, Inner Mongolia, Shaanxi, Sichuan, Yunnan, Xinjiang, Qinghai and Tibet.
For solar power, South Asia has the ideal combination of both high solar insolation and a high density of potential customers.
According to preliminary data from the US Energy Information Administration, renewable energy accounted for about 12.6% of total primary energy consumption and about 19.8% of the domestically produced electricity in the United States in 2020.
The developing nations of Africa are popular locations for the application of renewable energy technology. Currently, many nations already have small-scale solar, wind, and geothermal devices in operation providing energy to urban and rural populations. These types of energy production are especially useful in remote locations because of the excessive cost of transporting electricity from large-scale power plants. The applications of renewable energy technology has the potential to alleviate many of the problems that face Africans every day, especially if done in a sustainable manner that prioritizes human rights.
Ensuring adequate energy supply to sustain economic growth has been a core concern of the Chinese government since 1949. The country is the world's largest emitter of greenhouse gases, and coal in China is a major cause of global warming. However, from 2010 to 2015 China reduced energy consumption per unit of GDP by 18%, and CO2 emissions per unit of GDP by 20%. On a per-capita basis, it was the world's 51st largest emitter of greenhouse gases in 2016. China is also the world's largest renewable energy producer. China is the largest producer of hydroelectricity, solar power and wind power in the world. The energy policy of China is connected to its industrial policy. The goals of China's industrial policy dictate its energy needs.
In Honduras, there is an important potential of untapped indigenous renewable energy resources. Due to the variability of high oil prices and declining renewable infrastructure costs, such resources could be developed at competitive prices.
A feed-in tariff is a policy mechanism designed to accelerate investment in renewable energy technologies by offering long-term contracts to renewable energy producers. This means promising renewable energy producers an above market price and providing price certainty and long-term contracts that help finance renewable energy investments. Typically, FITs award different prices to different sources of renewable energy in order to encourage development of one technology over another. For example, technologies such as wind power and solar PV are awarded a higher price per kWh than tidal power. FITs often include a "degression": a gradual decrease of the price or tariff in order to follow and encourage technological cost reductions.
The electricity sector in Colombia is dominated by large hydropower generation (65%) and thermal generation (35%). Despite the country's large potential in new renewable energy technologies, this potential has been barely tapped. A 2001 law designed to promote alternative energies lacks certain key provisions to achieve this objective, such as feed-in tariffs, and has had little impact so far. Large hydropower and thermal plants dominate the current expansion plans. The construction of a transmission line with Panama, which will link Colombia with Central America, is underway.
China is the world's leading country in electricity production from renewable energy sources, with over triple the generation of the second-ranking country, the United States. China's renewable energy sector is growing faster than its fossil fuels and nuclear power capacity, and is expected to contribute 43 percent of global renewable capacity growth. China's total renewable energy capacity exceeded 1,000GW in 2021, accounting for 43.5 per cent of the country's total power generation capacity, 10.2 percentage points higher than in 2015. The country aims to have 80 per cent of its total energy mix come from non-fossil fuel sources by 2060, and achieve a combined 1,200GW of solar and wind capacity by 2030.
The electricity sector in Peru has experienced large improvements in the past 15 years. Access to electricity has increased from 45% in 1990 to 96.4% in 2018, while service quality and efficiency of service provision improved. These improvements were made possible through privatizations following reforms initiated in 1992. At the same time, electricity tariffs have remained in line with the average for Latin America.
Renewable energy in developing countries is an increasingly used alternative to fossil fuel energy, as these countries scale up their energy supplies and address energy poverty. Renewable energy technology was once seen as unaffordable for developing countries. However, since 2015, investment in non-hydro renewable energy has been higher in developing countries than in developed countries, and comprised 54% of global renewable energy investment in 2019. The International Energy Agency forecasts that renewable energy will provide the majority of energy supply growth through 2030 in Africa and Central and South America, and 42% of supply growth in China.
The energy sector in Switzerland is, by its structure and importance, typical of a developed country. Apart from hydroelectric power and firewood, the country has few indigenous energy resources: oil products, natural gas and nuclear fuel are imported, so that by 2013 only 22.6% of primary energy consumption will have been covered by local resources.
In 2018, Nigeria's primary energy consumption was about 155 Mtoe. Most of the energy comes from traditional biomass and waste, which accounted for 73.5% of total primary consumption in 2018. The rest is from fossil fuels (26.4%) and hydropower.
Energy use and development in Africa varies widely across the continent, with some African countries exporting energy to neighbors or the global market, while others lack even basic infrastructures or systems to acquire energy. The World Bank has declared 32 of the 48 nations on the continent to be in an energy crisis. Energy development has not kept pace with rising demand in developing regions, placing a large strain on the continent's existing resources over the first decade of the new century. From 2001 to 2005, GDP for over half of the countries in Sub Saharan Africa rose by over 4.5% annually, while generation capacity grew at a rate of 1.2%.
In 2013, renewable energy provided 26.44% of the total electricity in the Philippines and 19,903 gigawatt-hours (GWh) of electrical energy out of a total demand of 75,266 gigawatt-hours. The Philippines is a net importer of fossil fuels. For the sake of energy security, there is momentum to develop renewable energy sources. The types available include hydropower, geothermal power, wind power, solar power and biomass power. The government of the Philippines has legislated a number of policies in order to increase the use of renewable energy by the country.
