What are ways Renters (of a house) can get into alternative energy? - lemmywinks.com

Are there portable wind turbines and/or solar panels I can put up in my very bright dusty back yard?

Am a renter. Recently got two solar panels installed, maxing out at about 600 watts. It’s called a balcony power plant and you essentially just plug it into an ordinary outlet.
Could you elaborate on the setup you used? I am in a similar boat and thinking about doing this.
