1. alternative energy

   Renewable energy is energy that is collected from renewable resources that are naturally replenished on a human timescale. It includes sources such as sunlight, wind, the movement of water, and geothermal heat. Although most renewable energy sources are sustainable, some are not. For example, some biomass sources are considered unsustainable at current rates of exploitation. Renewable energy often provides energy for electricity generation to a grid, air and water heating/cooling, and stand-alone power systems. Renewable energy technology projects are typically large-scale, but they are also suited to rural and remote areas and developing countries, where energy is often crucial in human development. Renewable energy is often deployed together with further electrification, which has several benefits: electricity can move heat or objects efficiently, and is clean at the point of consumption. In addition, electrification with renewable energy is more efficient and therefore leads to significant reductions in primary energy requirements.From 2011 to 2021, renewable energy has grown from 20% to 28% of global electricity supply. Fossil energy shrunk from 68% to 62%, and nuclear from 12% to 10%. The share of hydropower decreased from 16% to 15% while power from sun and wind increased from 2% to 10%. Biomass and geothermal energy grew from 2% to 3%. There are 3,146 gigawatts installed in 135 countries, while 156 countries have laws regulating the renewable energy sector. In 2021, China accounted for almost half of the global increase in renewable electricity.Globally there are over 10 million jobs associated with the renewable energy industries, with solar photovoltaics being the largest renewable employer. Renewable energy systems are rapidly becoming more efficient and cheaper and their share of total energy consumption is increasing, with a large majority of worldwide newly installed electricity capacity being renewable. In most countries, photovoltaic solar or onshore wind are the cheapest new-build electricity.Many nations around the world already have renewable energy contributing more than 20% of their total energy supply, with some generating over half their electricity from renewables. A few countries generate all their electricity using renewable energy. National renewable energy markets are projected to continue to grow strongly in the 2020s and beyond. Studies have shown that a global transition to 100% renewable energy across all sectors – power, heat, transport and desalination – is feasible and economically viable. Renewable energy resources exist over wide geographical areas, in contrast to fossil fuels, which are concentrated in a limited number of countries. Deployment of renewable energy and energy efficiency technologies is resulting in significant energy security, climate change mitigation, and economic benefits. However renewables are being hindered by hundreds of billions of dollars of fossil fuel subsidies. In international public opinion surveys there is strong support for renewables such as solar power and wind power. But the International Energy Agency said in 2021 that to reach net zero carbon emissions more effort is needed to increase renewables, and called for generation to increase by about 12% a year to 2030.

1. alternative energy

   Alternative energy refers to any form of energy that is an alternative to traditional fossil fuel sources like oil, coal, or natural gas. This can include renewable and sustainable sources such as solar, wind, hydroelectric, geothermal, or bioenergy. The purpose of alternative energy sources is to reduce emissions, decrease reliance on non-renewable resources, and provide more environmentally-friendly options for power generation.

1. Alternative energy

   Alternative energy is any energy source that is an alternative to fossil fuel. These alternatives are intended to address concerns about such fossil fuels. The nature of what constitutes an alternative energy source has changed considerably over time, as have controversies regarding energy use. Today, because of the variety of energy choices and differing goals of their advocates, defining some energy types as "alternative" is highly controversial. In a general sense, alternative energy as it is currently conceived, is that which is produced or recovered without the undesirable consequences inherent in fossil fuel use, particularly high carbon dioxide emissions, an important factor in global warming. Sometimes, this less comprehensive meaning of "alternative energy" excludes nuclear energy.

Examples of alternative energy in a Sentence

1. Martin McPhee:

   Everyone thought (Tesla founder) Elon Musk was building a car company, but now we find he is building an alternative energy company.

2. Ray Mabus:

   It gives us a war fighting edge, energy can be used as a weapon. We need an American home grown source of alternative energy. We need one that is not subject to the wild price swings of conventional fuel, which are set in the world market. We need ones that can’t be used against us.

3. Vivien Yang:

   It is nearly impossible to influence the oil price long-term by freezing production as unconventional oil and gas and alternative energy may enter the market to bring down the price, the recent failed OPEC attempt to freeze production may cause grief from oil producers, but in reality even if it was successful its long term effect is doubtful.

4. liam mahone:

   if you fart in a jar and give it to someone with a note saying,"open for a blast ftom the past." that would count as a present item with a past-tence gift in it--of which holds no value, unless you can make it into an alternative energy source... then everybody wins, apart from the one who opened it of course.

5. Yoon Jong-Keun:

   The shutdown of 10 old coal power plants will not affect the country's power supply as we can replace them with alternative energy like biomass and renewables gradually.
