Wind is a favorite of some for renewable energy. Google has its airborne wind system Makani.

Altaeros Energies is a Helium buoyant system that deploys in containers.

Low Cost

The Altaeros BAT reduces the second largest cost of wind energy – the installation and transport cost – by up to 90 percent, through a containerized deployment that does not require a tower, crane, or cement foundation. Combined with significant increases in energy output, and flexible deployment options, the BAT is designed to significantly reduce the levelized cost of energy for remote power customers.

Mobility and Rapid Deployment

The Altaeros BAT is shipped in two standard containers and can be installed and producing power in under twenty-four hours. Easy transport, setup, and redeployment offers new mobility that is not feasible with tower-mounted wind turbines.

One of the nice things about the BAT is you can put other things up at that altitude.

Additional Revenue from Airborne Services

Much like other tethered aerostats, the Altaeros BAT can lift additional communication, surveillance, and sensory equipment alongside the turbine to provide additional services for remote sites. The BAT provides a line of sight over 60 miles in any direction, offering a powerful platform that fixed towers cannot reach. The addition of payload equipment does not affect the stability or power output of the system.
