Cost Overrun

Wave Energy is one of the niche Water Energy Technologies that is still in its infancy stage in terms of technology maturity.Wave Energy has been around a long time with around 350 patents being granted for this technology and around 200 startups working on this renewable energy form.Wave Energy basically derives power from the movement of waves to generate electricity or power.Wave Power exists due to the differences in the speed of ocean water and wind power.The energy is transferred by the Wind Energy to the Waves which can be utilized to generate power.A wide variety of wave energy generators like buoys,underwater devices are being developed to harness the power of the waves in a cost efficient manner.Wave Energy Research is concentrated mainly in the United Kingdom which has made tidal and wave power central to meeting its 2020 European goal for renewable energy.Edinburgh in UK has become a center of wave energy development and EMEC has developed Cornwall as an important site for demonstration of wave energy projects.Some of the wave power companies are listed on the stock market as well.Due to the technology immaturity ,most of these stocks are micro cap and not an investible class for big investors.

Wave Energy is one of the niche renewable energy technologies which is still in its infancy stage.While other forms of alternative energy like solar,wind and biomass see hundreds of billions of dollars in investment each year,wave energy does not see even $1 billion in investment.This is because Wave Energy is still much behind in the technology curve in terms of costs and reliability.Also there are many varied approaches and technologies to harness the power of the ocean waves.However developed countries like UK are promoting this renewable energy since it has huge potential like solar and wind energy.Given the energy shortages that we are facing,we need to promote all forms of sustainable green energy and wave energy definitely has strong promise.Here we present the various pros and cons of wave energy

The Cons of Geothermal Power are winning over the Pros in the last few years due to a number of factors.The main reasons are the long gestation time in building the geothermal energy plants,small developers,financing and regulation problems.Despite geothermal having huge potential these drawbacks have resulted in only 10 GW of geothermal energy being installed worldwide despite almost 30 years of commercial development.Most of the geothermal companies which are small developers have been devastated by the above problems.Canadian companies which are the leaders in consolidating the fragmented industry like Ram Power and Magma Power are facing huge problems.While Ram Power saw its CEO go,Magma is now looking at other renewable energy opportunities.Magma Power has decided to merge with Plutonic Power which is a small hydro and wind company as geothermal energy looks more or less a dead end.

Type of Renewable Energy have been increasing with development in Technology and the imperative of using Alternative Energy as Fossil Fuels deplete and increase in costs.Besides Global Warming has made the benefits of Renewable Energy seem more attractive with each passing year.Note though there are many niches Renewable Energy types,the Three Major Forms of Renewable Energy are Solar Energy,Wind Energy and Biomass Energy (Biofuels).Nuclear and Hydro Energy are not considered as Renewable Energy according to the strict definition of Renewable Energy.However Hydro and Nuclear Energy both are responsible for more than 15% of global electricity production each.The clean energy industry saw a 30% increase in investments to $243 billion in 2010 which was another record year for Renewable Energy Capacity addition.Around 18 GW of Solar Energy and 38 GW of Wind Energy were installed with Solar Energy Capacity increasing by a whopping 150% from 2009.\wind power continued to lead at $95 billion. The solar sector is experiencing significant growth, with investments growing at 53% to $79 billion (source Pew).

Geothermal Energy is regarded as a poor cousin to its more glamorous cousins Wind and Solar.Geothermal Energy Capacity has been installed and the growth rate is a pathetic 3-4% compared to the over 50% CAGR seen for solar energy and around 30% for Wind Energy.However Geothermal Energy possesses one attribute that the others do not.Its 24 hour generation capability is a massive plus compared to the intermittent nature of Wind and Solar Energy.However long project development time and large capital investments have deterred fast growth in geothermal energy in the world.However some countries like Iceland,Indonesia,Philippines and USA have a strong geothermal energy industry.Note Geothermal Energy has massive use as a heating source for homes and offices,however this article mainly talks from the view of Electricity Generation.

Geothermal Energy is the proverbial poor cousin to wind and solar energy.Only 10 GW of Geothermal Energy Capacity has been installed and the growth rate is a pathetic 3-4% compared to the over 50% CAGR seen for solar energy and around 30% for Wind Energy.Geothermal Energy produces electricity at a reasonable cost in mature locations and unlike Solar,Wind does not suffer from intermittency problems.However a number of problems dog geothermal energy development.Despite huge promise,Geothermal Energy faces a slow painful death and unless something dramatic happens will remain a niche renewable energy source.Canadian companies which are the leaders in consolidating the fragmented industry like Ram Power and Magma Power are facing huge problems.While Ram Power saw its CEO go,Magma is now looking at other renewable energy opportunities.
