Renewable Energy 101 - National GeographicSustainable Energy Resources -
Securing energy supply, and ensuring that this is done in an economically and environmentally sustainable manner, has become a priority for all countries. This is known as energy security. The use of sustainable energies makes it possible to diversify energy sources and take advantage of natural resources and phenomena to produce other types of energy.
Moreover, its sources are inexhaustible and heterogeneous. For this reason, the use of this type of energy reduces energy dependence. The concept of energy security implies that this supply must be capable of supplying all people and sectors of activity, and that it must be carried out in a sustainable way.
Energy efficiency is also relevant in this regard. Technology and digital transformation are once again fundamental here to provide tools that facilitate the transformation of the energy model and efficient consumption. Sustainable energy has also become an important source of employment , already employing According to this study, the labor market associated with solar energy stands out, which employed 4.

Fossil fuel use is also unsustainable for our health and the safety of the environment. For example, emissions from coal-fired power plants include particulate matter and mercury, and are responsible for respiratory illness and premature death especially in vulnerable populations like children and the elderly [8].
Due to the Clean Air Act, the United States has instated more measures to regulate pollutants than developing countries. Unfortunately, coal plant emissions are not just local, meaning that longer-lived pollutants like fine particulate matter, mercury, and cancer-causing chemicals get transported from countries with poorer air quality standards to other areas of the globe [9].
Further, coal has a considerable hidden cost associated with economic, health, and environmental impacts.
It is estimated that the combined cost of mining, transportation, processing, and combustion to the United States alone can range from billion to over billion dollars annually [11].
In other words, we pay a high price for coal in the form of health care costs and higher taxes but coal appears cheap only because the price is not directly on our electricity bills.
If we account for these hidden costs, coal-generated electricity is three times more expensive than what we pay directly and suddenly renewable sources of electricity are economically competitive with coal [11].
Human fossil fuel use is also contributing to global climate change: burning fossil fuels produces the greenhouse gas carbon dioxide as a byproduct. There is increasing evidence that the carbon dioxide produced from burning ancient fuels is accumulating in the atmosphere faster than the land and oceans can take it up.
In alone, the world emitted This puts the welfare of future human societies at risk because carbon dioxide accumulation in the atmosphere is associated with sea level rise, the melting of glaciers and sea ice, and increases in the frequency of heat waves, droughts, and extreme weather events [12].
These facts paint a grim picture, so what are the alternatives to fossil fuels? While we cannot change the basic need for energy to power our lives, we can continue to develop technology to change where that energy comes from.
Fossil fuels took millions of years to form, and it will take that much time for them to be replenished. Yet, our need for energy is immediate. From national and energy security perspectives, it will be important to increase domestic fossil fuel production in the short term, but this still does not address the issues relating to finite supplies, air quality, and human-caused climate change.
Instead of continuing to rely upon them in the long term, domestic fossil fuels can be used in the short-term to bolster renewable energy technologies until these technologies are dependable enough to stand on their own.
But if there is so much energy around us, why is it so hard for us to shift to sustainable energy sources? As of now, renewable energy technologies are not optimally designed or economically profitable partially because few financial resources are being channeled into their development.
That said, all technologies that humans enjoy today including cars, telephones and electricity! were once in a stage too young to be considered reliable or profitable for the mass market. However, continued investments gave researchers the resources and opportunities to develop these technologies and maximize performance and functionality.
There will never be a magic solution that eliminates all the negative consequences of our energy demands, but we can make educated choices about using and developing energy sources that significantly reduce the social and environmental impacts of our energy use.

| What is Sustainable Energy: Sources, Definition & Examples | Inspire Clean Energy | Governments can accelerate energy system transformation by leading the development of infrastructure such as long-distance electrical transmission lines, smart grids, and hydrogen pipelines. Carbon pricing such as a tax on CO 2 emissions gives industries and consumers an incentive to reduce emissions while letting them choose how to do so. For example, they can shift to low-emission energy sources, improve energy efficiency, or reduce their use of energy-intensive products and services. The scale and pace of policy reforms that have been initiated as of are far less than needed to fulfil the climate goals of the Paris Agreement. Countries may support renewables to create jobs. Six million jobs would be lost, in sectors such as mining and fossil fuels. Raising enough money for innovation and investment is a prerequisite for the energy transition. Most studies project that these costs, equivalent to 2. However, this goal has not been met and measurement of progress has been hampered by unclear accounting rules.

The fight against climate change and the protection of biodiversity are two global challenges that can only be addressed through the transition to a model based on sustainable energy. The commitment to sustainable and non-polluting energy sources will make it possible to reduce greenhouse gas emissions and achieve the objectives laid out in the Paris Agreement. In addition, the sustainable energy model brings undeniable benefits for people's health in terms of improved air quality, which translates into a lower incidence of air-related diseases. What's more, the transition to sustainable energy sources minimizes dependence on large quantities of water, which helps conserve water resources and prevent water scarcity. In short, sustainable energy comes from renewable sources, so it respects natural resources , and its production process does not generate an environmental impact or the emission of greenhouse gases or other pollutants. Securing energy supply, and ensuring that this is done in an economically and environmentally sustainable manner, has become a priority for all countries. This is known as energy security.
