Hydro (Water-generated) Power



Water, readily and widely available, was the earliest source of significant power.  Harnessed by dams, wells, mills, pipelines and pumps waterpower is considered renewable, but not free.


Costs include aggregate, metals, minerals, and construction; damage to fish and wildlife habitat; damage to forestry; deliberate flooding affecting local populations; mercury poisoning and other flood impacts.  Additionally, there are the costs associated with distribution:  hydro poles and lines; impacted forestry and wildlife.


The benefits of electricity are widely accepted to be worth the costs, and today electricity is considered an essential service.



Pumped Storage Hydroelectric Power Stations


Pumped storage hydroelectric power stations include two reservoirs of water, the first reservoir at a higher altitude emptying over the electricity generating turbines into the second reservoir.  Then on off-peak hours the water is pumped back to the first.  It is not unreasonable to use alternative power sources such as wind or solar to power the pumps in a stored hydro facility such as Dinorwig Power Station in Wales.

Liquid Storage Electric Power Stations


Air turns to liquid when cooled down to -196°C (-320˚F), and can then be stored very efficiently in insulated, low pressure vessels. Exposure to ambient temperatures causes rapid re-gasification and a 700-fold expansion in volume, which is then used to drive a turbine and create electricity without combustion.  Highview Power’s patented technology can be used in conjunction with out waste heat and cold energy to generate electricity.

Can We Compromise – Hydro Lines AND Trees?


According to Hydro One’s website, tree contacts account for more than 30 percent of power outages in Ontario and can also cause fires and property damage.  Hydro One’s mission is to deliver electricity safely, reliably and in a cost-effective manner to customers and communities across Ontario.  Keeping vegetation a safe distance away from power lines is necessary for public and worker safety.  It is also a requirement of operating and reliability standards established by regulators, provincial agencies, and utility partners across North America.


Unfortunately, Hydro One’s mission sometimes involves cutting trees and shrubs under or near the transmission and distribution lines.  It also entails using a herbicide (Garlon RTU registration #29334) – with the permission of the landowner – to control suckering from stumps and stems of cut trees and brush.   The goal is to limit tree maintenance to every 6 years and maximize hydro system up-time.

However, today’s society can ill afford to lose trees.  Pollution levels of carbon dioxide, drastic temperature changes from climate change, concerns about fresh air and water are all offset by trees.  Trees are already at risk to foreign invaders like the emerald ash borer, Asian long-horned beetle and Japanese Viburnum beetle.  Hydro lines typically run parallel to roads and where trees are important to provide sound barriers, wind breaks and snow barriers.  Trees shield the eyes of drivers from a glaring sun.  They also provide habitat for birds, animals and insects and aid in water filtration and in the hydrological cycle through transpiration.  In short, trees give us fresh air to breathe, ease of passage on the roads, cool protected spaces to sit under and are esthetically pleasing to look at.  For the most part, we don’t want to cut them unless it is absolutely necessary.


So if Hydro One wants to cut trees on YOUR road is it absolutely necessary?  You must decide and work with Hydro One to solve the dilemma.
