1. Introduction What is sustainable energy? Sustainable energy is a form of energy that meets today’s demand for energy without putting them in danger of getting expired or depleted. It can be used over and over again. Sustainable energy should be widely encouraged as it does not cause any harm to the environment and is available widely free of cost. All renewable energy sources like solar, wind, geothermal and hydropower are sustainable sources of energy as they are stable and available in plenty.
2. Sustainable energy - too little too late? The idea of the energy transition originated in the 1980s and gained legislative support in Germany in 2010. The idea is good and also technically feasible. But it requires sacrifices and right now these sacrifices are politically unthinkable since most people don’t realize how critical the situation really is. What we are doing for the transition seems to be is too little and too late. So, what’s going to happen? The fact that we won’t attain the transition doesn’t mean returning to Middle Ages, but that in the future not everyone, and not even a majority of people, will have as much energy as we are used to having today. The sacrifices we refuse to make now will have to be made, and much larger, in the future.
3. Types of sustainable energy: 1. Solar energy - Solar energy works by capturing the sun’s energy and turning it into electricity for your home or business. The sun delivers more energy to the earth in one hour than is used worldwide in a year. We can harness this energy by using solar technologies.
2. Wind energy . Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth's surface, and the rotation of the earth. This wind flow can be "harvested" by modern wind turbines, and used to generate electricity.The term "wind energy" describes the process by which the wind is used to generate electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. this mechanical power can then be converted into electricity to power homes, businesses. Wind Energy is currently the largest contributing source of renewable energy in Ireland. The Irish Wind Energy Association (IWEA) was founded to promote and educate people about wind energy issues.
3. Geothermal energy Geothermal energy is the heat that is generated and stored in the Earth. It's a clean and sustainable energy source. This heat energy supplied to the ground can come from two main sources, the Earth's crust and the solar energy supplied by the sun.
Solar - The Earth's surface acts as a very large collector of solar energy, where the energy radiated from the sun is stored in the shallow layers of soil at the Earth's surface. This energy can be regarded as stored energy which stays relatively warm throughout the year - these sources are generally used for individual home heating systems. The earth’s crust - The Earth's structure is comprised of three main layers the Earth's crust, the mantle and the core. As we move deeper into the structure of the Earth the temperatures increase. Heat energy can also be due to the decay of radioactive isotopes such as uranium in different rock types. In volcanic areas such as Iceland geothermal energy is a main source of energy. In Iceland 87% of buildings obtain their heat requirements from geothermal sources. The hot rocks and hot springs from the active volcanic area heat water to produce steam which in turn drives large turbines to generate electricity.
4. Hydroelectric power Flowing water creates energy that can be captured and turned into electricity. This is called hydroelectric power. The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity. But hydroelectric power doesn't necessarily require a large dam.
4. The Benefits of Using Renewable Energy Sources: All energy sources have some impact on our environment. Fossil fuels, such as coal and oil, and natural gas do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions. Human activity is overloading our atmosphere with carbon dioxide and other harmful gases. These gases act like a blanket around earth, trapping heat. The result is Global warming which leads to a series of different issues, such as, stronger and more frequent storms, drought, sea level rise, and extinction.
5. Environmental Protection Agency - (EPA) The EPA was established in 1993 under the 1992 Environmental Protection Act, replacing the previous Environmental Research Unit. Their mission is to protect human health and the environment. The EPA has a wide range of functions to ensure Ireland’s environment is protected. It’s main responsibilities include: -
Environmental licensing Enforcement of environmental law Environmental planning, education and guidance Monitoring, analysing and reporting on the environment Regulating Ireland's greenhouse gas emissions Environmental research development Strategic environmental assessment Waste management Radiological protection
6. Sustainable Energy Authority of Ireland- (SEAI) SEAI is Ireland's national sustainable energy authority. They work with householders, businesses, communities and the government to create a cleaner energy future. Their aim is to make Ireland’s energy more sustainable, affordable and clean. To achieve this, Ireland must use less energy, move to clean energy, and innovate to create new solutions to try meet our energy needs. Since 2011, SEAI have supported a range of activities from home energy efficiency upgrades to ocean energy research. They have invested over 400 million in sustainable energy projects and continue to work towards Ireland’s energy goals.

8. The Future of Sustainable Energy in Ireland Ireland is leading the way to a clean energy future by embracing clean electricity, electric cars, smart networks, heat pumps and emerging technologies. In a way that was never possible before, Irish consumers are taking control of their own energy supply as homes and businesses transform into mini power stations. We are harnessing the power of solar, wind, wave and storage and using smart technology. These small and fundamental changes are the beginning of our energy revolution. We are already adopting new ways to generate and consume energy, including the way we drive our cars and heat our homes. In the home, we can harness the power of the sun with the introduction of solar panels to provide electricity and to heat our water. Solar Photovoltaic (PV) panels are becoming a common sight on Irish rooftops, providing clean energy from the sun. As well as solar energy, Ireland is adapting to a variety of renewable energies. By 2030, clean energy is expected to become the largest source in global electricity production — and wind generation is forecast to lead the way to meet the high demand for renewables in Ireland. When it comes to wind power, Ireland is a global pioneer. Wind energy now supplies over 20% of Ireland’s total annual electricity demand and at any one time. 2017 was a record-breaking year for installing wind energy capacity in Ireland and we have one of the highest levels of installed wind capacity relative to our wind consumption. By 2020, wind is expected to contribute between 37% and 40% of our renewable electricity.

10. Conclusion In conclusion sustainable energy is something I believe we need to take more seriously as it is crucial to the future of this planet. The main goals of sustainable development is to minimize the depletion of natural resources, to create development that can be sustained without causing further environmental harm and to modify existing developments to make them more environmentally friendly. It’s about improving the well being of everyone wherever they are. This means we want companies to expand, people to have the best jobs, everyone to afford nutritious foods wherever they live, quality and affordable education for everyone, freedom of speech without violence, and our economies to grow exponentially. We want to develop innovative technologies while keeping the environment safe. Renewable energy technologies are clean sources of energy that have a much lower environmental impact than conventional energy technologies. We need to use more sources of sustainable and renewable energy to try slow the global warming process and protect the environment.
