If you are concerned about the environment you are certainly thinking about your carbon footprint. The best way to live more responsibly is to look at your living style and energy consumption. Solar energy is sustainable but it is not enough. There are several other things worth thinking about to make your house green and energy-efficient. The first thing that most people think about is solar energy. Solar energy is great for the environment but it requires a considerable investment. The government does offer grants to homeowners that choose solar energy. It drives down the cost of installing solar panels. While this does reduce your reliance on electricity coming from fossil fuels, it can be improved further. There are energy storage solutions which are large batteries, that can store solar energy and provide electricity during the night. If you have large enough solar panels, the excess energy generated throughout the day can be used during the night. Another approach to make your home more energy efficient is to change your light bulbs. As trivial as it may sound, it can make a big difference. LED lights need 75% less electricity than regular incandescent light bulbs. If you want to take things even further, you can install sensors that will keep the lights on only when you are in the room. Lastly, you should consider replacing old appliances with energysaving appliances. Old appliances are anything but energy efficient. As technology evolved, newer appliances require less energy to run. You should take a look at all your appliances, especially the ones that you use the most, and determine their energy consumption. Based on that you can look for appliances that are more energy-efficient. Certainly, replacing all your appliances with new ones can be quite expensive. You do not have to replace all of them. You can start with the oldest ones and keep the ones that require very little power to run.
