Renewable energy is energy from renewable natural resources that are replenished on a human timescale. The most widely used renewable energy types are solar energy, wind power, and hydropower. Bioenergy and geothermal power are also significant in some countries. Some also consider nuclear power a renewable power source, although this is controversial. Renewable energy installations can be large or small and are suited for both urban and rural areas. Renewable energy is often deployed together with further electrification. This has several benefits: electricity can move heat and vehicles efficiently and is clean at the point of consumption. Variable renewable energy sources are those that have a fluctuating nature, such as wind power and solar power. In contrast, controllable renewable energy sources include dammed hydroelectricity, bioenergy, or geothermal power.
The economy of Norway is a highly developed mixed economy with state-ownership in strategic areas. Although sensitive to global business cycles, the economy of Norway has shown robust growth since the start of the industrial era. The country has a very high standard of living compared with other European countries. Norway's modern manufacturing and welfare system rely on a financial reserve produced by exploitation of natural resources, particularly North Sea oil. Among OECD nations, Norway has a highly efficient and strong social security system; social expenditure stood at roughly 22.6% of GDP.
Resource depletion is the consumption of a resource faster than it can be replenished. Natural resources are commonly divided between renewable resources and non-renewable resources. The use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion. The value of a resource is a direct result of its availability in nature and the cost of extracting the resource. The more a resource is depleted the more the value of the resource increases. There are several types of resource depletion, including but not limited to: mining for fossil fuels and minerals, deforestation, pollution or contamination of resources, wetland and ecosystem degradation, soil erosion, overconsumption, aquifer depletion, and the excessive or unnecessary use of resources. Resource depletion is most commonly used in reference to farming, fishing, mining, water usage, and the consumption of fossil fuels. Depletion of wildlife populations is called defaunation.
An environmental tax, ecotax, or green tax is a tax levied on activities which are considered to be harmful to the environment and is intended to promote environmentally friendly alternatives via economic incentives. One notable example is a carbon tax. Such a policy can complement or avert the need for regulatory approaches. Often, an ecotax policy proposal may attempt to maintain overall tax revenue by proportionately reducing other taxes ; such proposals are known as a green tax shift towards ecological taxation. Ecotaxes address the failure of free markets to consider environmental impacts.
A non-renewable resource is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. An example is carbon-based fossil fuels. The original organic matter, with the aid of heat and pressure, becomes a fuel such as oil or gas. Earth minerals and metal ores, fossil fuels and groundwater in certain aquifers are all considered non-renewable resources, though individual elements are always conserved.
The resource curse, also known as the paradox of plenty or the poverty paradox, is the hypothesis that countries with an abundance of natural resources have lower economic growth, lower rates of democracy, or poorer development outcomes than countries with fewer natural resources. There are many theories and much academic debate about the reasons for and exceptions to the adverse outcomes. Most experts believe the resource curse is not universal or inevitable but affects certain types of countries or regions under certain conditions. As of at least 2024, there is no academic consensus on the effect of resource abundance on economic development.
Petroleum Revenue Tax (PRT) is a direct tax collected in the United Kingdom. It was introduced under the Oil Taxation Act 1975, soon after Harold Wilson's Labour government returned to power and in the immediate aftermath of the 1973 energy crisis, and was intended to ensure "fairer share of profits for the nation" from the exploitation of the UK's continental shelf, while ensuring a "suitable return" on the capital investment by oil companies.
A windfall tax is a higher tax rate on profits that ensue from a sudden windfall gain to a particular company or industry.
Norway is a large energy producer, and one of the world's largest exporters of oil. Most of the electricity in the country is produced by hydroelectricity. Norway is one of the leading countries in the electrification of its transport sector, with the largest fleet of electric vehicles per capita in the world.
Iceland is a world leader in renewable energy. 100% of the electricity in Iceland's electricity grid is produced from renewable resources. In terms of total energy supply, 85% of the total primary energy supply in Iceland is derived from domestically produced renewable energy sources. Geothermal energy provided about 65% of primary energy in 2016, the share of hydropower was 20%, and the share of fossil fuels was 15%.
Norway is a heavy producer of renewable energy because of hydropower. Over 99% of the electricity production in mainland Norway is from 31 GW hydropower plants. The average hydropower is 133 TWh/year. There is also a large potential in wind power, offshore wind power and wave power, as well as production of bio-energy from wood. Norway has limited resources in solar energy, but is one of the world's largest producers of solar grade silicon and silicon solar cells.
Non-tax revenue or non-tax receipts are government revenue not generated from taxes.
The Minerals Resource Rent Tax (MRRT) was a resource rent tax formerly imposed by the government of Australia on profits generated from the mining of non-renewable resources in Australia. It was a replacement for the proposed Resource Super Profit Tax (RSPT).
In 2019, the total energy production in Indonesia is 450.79 million tonnes of oil equivalent, with a total primary energy supply of 231.14 million tonnes of oil equivalent and electricity final consumption of 263.32 terawatt-hours. From 2000 to 2021, Indonesia's total energy supply increased by nearly 60%.
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.
The petroleum fiscal regime of a country is a set of laws, regulations and agreements which governs the economical benefits derived from petroleum exploration and production. The regime regulates transactions between the political entity and the legal entities involved. A commercial or legal entity in this context is commonly an oil company, and two or more companies may establish partnerships to share economic risks and investment capital.
A mineral tax is any tax, excise or other government-imposed fee on mineral resources, such as crude oil or ores. The taxation of minerals serves as a price to extract scarce resources, such as petroleum and crude oil, which are owned by the government. By taxing minerals, the government is able to secure a certain share of the minerals. Mineral taxes should possess neutral characteristics, to maintain incentives for investors and maximize the tax revenue for the government, while minimizing the variability and uncertainty of the amount of tax money collected. Since the 1950s it is more common to use special taxes like royalty taxes with ordinary taxes. Taxing minerals is the more economic approach to incentivise environmental thinking and an alternative to intervene in the market directly.
Renewable energy in South Africa is energy generated in South Africa from renewable resources, those that naturally replenish themselves—such as sunlight, wind, tides, waves, rain, biomass, and geothermal heat. Renewable energy focuses on four core areas: electricity generation, air and water heating/cooling, transportation, and rural energy services. The energy sector in South Africa is an important component of global energy regimes due to the country's innovation and advances in renewable energy. South Africa's greenhouse gas (GHG) emissions is ranked as moderate and its per capita emission rate is higher than the global average. Energy demand within the country is expected to rise steadily and double by 2025.
The environmental impact of bitcoin is significant. Bitcoin mining, the process by which bitcoins are created and transactions are finalized, is energy-consuming and results in carbon emissions, as about half of the electricity used in 2021 was generated through fossil fuels. Moreover, bitcoins are mined on specialized computer hardware with a short lifespan, resulting in electronic waste. The amount of e-waste generated by bitcoin mining is comparable to that generated by the Netherlands. Scholars argue that bitcoin mining could support renewable energy development by utilizing surplus electricity from wind and solar. Bitcoin's environmental impact has attracted the attention of regulators, leading to incentives or restrictions in various jurisdictions.
