Renewable energy is energy that is obtained from renewable sources that are replenished naturally on a human timescale and don't deplete with time while using them. It includes all sources and forms of energy that are mainly from renewable sources. Our world has been using non renewable energy sources for a long time and we all know that non renewable sources such as fossil fuel etc once depleted can never be renewed. So we have to use them carefully and need to shift from non-renewable to renewable as soon as possible. Many countries of the world and big giants and superpowers like US and Russia and China are taking best steps and moving forward towards the renewable energy which is good for our planet earth and for our environment because this is the only way we can save our earth from global warming and green house gases. Following are the best steps taken by governments of different countries to move form non renewable to renewable energy and save our earth and environment.
Examples of renewable energy.
*sunlight or solar energy
*Wind energy
*hydro energy (Rain)
*Tides
*Geothermal heat

United States of America(USA) and renewable energy
The Donald Trump administration approved a solar project that will be the eighth in the world and the largest in the United States. It will be built in Las Vegas and will provide renewable energy to an estimated 260,000 homes there.The cost is estimated at 1billion. According to the US Department of the Interior, the three-year project will create 713 million in economic activity for Las Vegas residents and provide them with 900 new construction jobs. In addition, 1,100 other administrative and support jobs will be created. The project will generate 690 megawatts of electricity and 7,100 acres of government land have been acquired for it, located 25 miles north of downtown Las Vegas.
There is not only increasing investment in wind and solar power, but it is also creating new employment opportunities.
The administration of former US President Barack Obama launched a ambitious campaign called Sunshot Initiative in 2010. The main objective of the campaign was to reduce the cost of grid-linked solar energy to the level of electricity already available in the power grid. Per unit. They vowed to bring down the price of solar energy by six cents by 2020. So by 2017, the U.S. would reduce the price of solar energy for domestic use from 52 cents to forty cents and the price of solar energy for commercial use by sixteen cents. Bring up to eleven cents. By the end of this year, the US administration wanted to bring these figures down further to ten and eight cents, respectively. It is possible that these goals have been achieved so far.

| Renewable energy and solar energy |
Today, solar energy is an important source of electricity supply and is part of the distribution systems of the world. I have a tendency to spread further. Texas, Colorado and other US states have successfully integrated solar and other renewable energy sources into the grid, with more than 50 percent of electricity now being generated from renewable sources in some parts of the year.
*From where world will get its energy?
The International Organization for Renewable Energy (IRENA) said last year that 83 per cent of the solar energy projects to generate electricity in 2020 would provide cheaper electricity than even the cheapest fuel. According to the agency, the average tariff per unit for solar energy projects will be 4.8 cents, which is less than the target set by the Sunshot Initiative. This year, not only financial but also operational power will be revolutionized.
In the United States over the past 12 years, with the help of government policies, American investors and inventors have made significant progress in developing and adopting key technologies for environmentally friendly energy. As a result, in 2012, for the first time in almost 20 years, carbon emissions were at an all-time low. That is, its capacity has been improved. The country had the largest source of new power generation capacity in 2012, accounting for forty-four percent of all new installations. In total, the United States has installed 60 gigawatts of wind power, enough to power 15 million households.
According to the wind-generated energy organization, the growth in wind power generation there has boosted American industrialization in the sector, and by 2012, more than 80,000 people were employed in the sector in the United States. And there has been a significant reduction in the cost of wind power generation technologies. Since 2008, the cost of solar panels has dropped by 75 percent and solar installations have increased by 13 percent. In addition, US government support has helped launch some of the world's largest solar projects.
*Getting energy from renewable sources in the United States
California has the largest market share of solar in the United States, but other states, especially Massachusetts, New York and Texas, are rapidly increasing their solar power installations. Solar energy now costs coal and pollutes. Is competing with other energy sources. That's why the installed capacity of solar energy increased by 16% in 2015 compared to 2014. The Association of Solar Energy Industries says that solar energy in the United States is growing at a record pace.
In the United States, renewable energy projects are allowed on federal lands. Since 2009, the number of approved projects on government lands has actually increased from zero to almost fifty. There has also been an increase in solar, wind and underground heating projects. These include transmission lines and infrastructure up to established power grids. Upon completion, the projects will add 13,300 megawatts of electricity - enough to power 4.6 million homes.
Wind power is now the largest source of pollution-free energy in the United States. In terms of current production capacity, it has now surpassed hydropower. Wind power generation is now on the rise in high-powered states, especially Texas and the Midwest. The U.S. Energy Information Administration estimates that the power grid's power generation capacity increased in 2016, accounting for 60 percent of all power from solar sources.
As prices fall and technology improves, wind power will compete with power from conventional sources. From 2008 to 2017, the prices of wind turbines were reduced by twenty to forty percent. In some places, such as Kolo Radu, wind power is replacing the power generated by conventional power plants. Except for the United States, more electricity is generated from wind than any other country.
U.S. statistics show that between 2005 and 2017, emissions from polluting gases in the United States actually decreased by 13 percent, while the U.S. economy grew by more than 19 percent. The development and use of innovative energy technologies. It also includes improvements in nuclear energy, shale gas, coal-fired power generation technologies, renewable energy sources, power storage in batteries and increased energy efficiency. With affordable, reliable and clean energy Better performance is creating new jobs in the United States and the US government is helping companies look for new opportunities in the international market.
The number of fuel-efficient vehicles there has also increased due to US government investments and fuel-saving standards. According to experts, this situation will further improve. Under the new fuel economy standards, the average fuel efficiency for motor cars and trucks will almost double. By 2025, average vehicle performance will be around 55 miles per gallon (4.28 liters per 100 kilometers).
As a result of these standards, more efficient cars and trucks are being built. When these standards are fully implemented in 2025, they will reduce US oil exports by 2.2 million barrels per day. Carbon pollution will be reduced to six billion metric tons. It should be noted that this amount is equal to the total carbon emissions in the United States during 2013.

In addition to improving fuel economy, there is a growing demand for modern vehicles in this country. Demand for plug-in electric vehicles has grown faster than the initial demand for hybrid vehicles due to lower prices and improved export market. Prices have dropped by fifty per cent.
Renewable energy sources, which currently employ more than half a million people worldwide, are proving to be employment machines for the global workforce. Of these, more than 1.8 million workers are solar energy, wind power. Works in the field of power generation from sources such as generation, bioenergy and geothermal. More importantly, the employment opportunities in this sector increased globally by more than 5% between 2014 and 2015 and then this trend continued. Or work on hydroelectric projects, including the construction of dams, their operation, and the maintenance of vast reservoirs of water for power generation.
*China, Brazil and United States of America
China, Brazil and the United States are at the forefront of new employment opportunities in the renewable energy sector. However, China is at the forefront of employment in the solar energy sector in the world. According to the International Renewable Energy Agency (IRENA), renewable and environmentally friendly energy sources are sectors that have become "employment machines" for the global workforce due to the continuous creation of new employment opportunities.
One of the main reasons for the growing trend of global reliance on renewable energy sources is that the cost of such eco-friendly energy installations is much lower today than in the past. The political situation has also improved considerably to make economic decisions possible. Experts hope that this trend towards green energy will not only continue in the future but also in the field of green energy in more and more countries. Progress is expected to be made in achieving the goals set out in the Paris Agreement on the World Environment.

Currently, most of the world's renewable energy workers are employed in solar energy. The number of these workers is seventy three lakhs. A total of 8.2 million of them are said to be full-time workers in the sector. The country is China. The total number of workers in this sector in China is said to be around 71 lakhs.
After China, Japan is second with more than 1.5 million workers, the United States is third with about 200,000 workers and Bangladesh is fourth with more than 1.5 million workers. Encouragingly, in the last few years alone, nearly 700,000 solar home systems have been sold in rural Bangladesh, enabling people to meet their daily energy needs through renewable sources. Millions of Bangladeshis were among those who, for the first time in their lives, had access to electricity through such sources. , India and Brazil.
According to a report, experts expect that employment opportunities in the global renewable energy sector will increase further in the coming years and by 2030, the total number of workers in this economic sector will exceed 24 million.
Surprisingly, renewable energy sources around the world have seen a 3% increase in power generation, transmission interruptions and construction delays during the Covid-Nine outbreak. According to the Report on the Global Energy Situation, power generation from renewable energy sources has been prominent during the Karunaki epidemic due to factors such as flexibility and resistance to power transmission compared to other sources.
According to the report, global power generation from this sector has increased from 26% to 30% which is a significant rate despite all obstacles. The sector has grown at a rate of 5%. In addition, it is estimated that renewable energy production will increase this year with the completion of licensed and under-construction projects worldwide.
