Green Energy is a great way to save money and help save raw materials such as gas and electricity. Companies and engineers debate whether Green Energy or Energy Star products are worth using and whether the products will save them money. Green Energy is used to save energy, such as electricity or gas. Energy Star is used to seal a home and prevent heat and air conditioning from escaping from a home. Energy Star is a rating that companies give to products that tell customers they are saving energy. Green energy is a renewable energy source because it helps save energy and uses the earth's resources to create and save energy without wasting money (Bishop). Green energy is energy produced with a much less negative impact on the earth. Green energy is great for saving the earth from any harmful fossil fuels that humans might burn. Home and building owners think that these Energy Star products are harmful because the initial cost of the products is much higher than that of regular products. Energy Star products may cost more up front, but they save money on consumers' bills in the long run. Solar energy is probably the cleanest and most reliable renewable energy source. Solar energy is harnessed by solar panels that transform the sun's rays into electricity or heated water. Electricity can be used to power lights in your home or business and to power anything else that uses energy within a home or business. The heated water provided by these solar-powered photovoltaic panels can be used for heating within a home or business, but can also be used for hot water for sinks and showers within a consumer housing. All this without the gas or electricity costs of running your water heater and furnace all day. Wind power is also another… paper medium… a great way to save money on gas and electricity bills because these Energy Star products help seal a home and don't let air conditioning or the heat. Green energy helps save the earth because it uses renewable energy and saves the earth's atmosphere from fossil fuels or coal fumes. Installing the tankless water heater would save money under certain circumstances, so it should be tested to see if it would end up saving money or costing you money. Tankless water heaters come with technology and multiple sensors to tell the water heater whether it should start working and create hot water or not to save free gas or electricity that runs the system. To choose which water heater would be best you should go through many things to understand if your home is suitable to install the system and save energy. Works cited
