Steps Taken So Far: A Review of Wind Energy Development

The growth of wind energy over the past few decades has been nothing short of remarkable. Global wind energy capacity has soared from a modest 6.1 GW in 1996 to a staggering 743 GW by the end of 2020, as the Global Wind Energy Council reported. This growth is the result of several key steps:

  1. Expansion of Wind Farms: Countries worldwide have invested heavily in developing wind farms, both onshore and offshore. In 2020 alone, China installed a record 52 GW of wind power, more than half the total global capacity added that year. Meanwhile, the UK leads the world in offshore wind capacity, with over 10 GW installed by the end of 2020.
  2. Technological Advancements: The efficiency of wind turbines has significantly improved due to technological advancements. Modern turbines are up to 40% efficient in converting wind’s kinetic energy into electrical energy, nearly twice the efficiency of turbines in the early 2000s.
  3. Policy Initiatives: Governments worldwide have implemented many policies to promote wind energy. These include renewable portfolio standards, feed-in tariffs, tax credits, and green certificates. For instance, the Production Tax Credit in the US has stimulated significant wind energy growth since its introduction in 1992.
  4. Investments in Infrastructure: Billions of dollars have been invested in infrastructure to accommodate the integration of wind power into the electricity grid. Denmark, for example, invested heavily in its grid infrastructure, allowing it to generate nearly 50% of its electricity from wind power in 2020.
  5. Public Engagement and Education: Many countries have launched public engagement and education initiatives to promote the acceptance of wind energy. These have included information campaigns, public consultations, and community benefit programs.
  6. International Cooperation: Global cooperation in wind energy development has also been significant. Establishing international bodies such as the International Renewable Energy Agency (IRENA) and the Global Wind Energy Council (GWEC) has facilitated sharing of best practices, policy frameworks, and technology advancements.

Despite the tremendous growth, wind energy still represents a small portion of global power generation. At the end of 2020, wind energy accounted for around 5.6% of total global electricity production, according to the International Energy Agency. While promising, the path ahead is strewn with challenges that must be surmounted to completely leverage the potential of wind power.

Challenges Faced

Despite the promising growth and potential of wind energy, the sector is not without its challenges:

  • Intermittency: Wind energy is subject to the variability of wind speeds, which are influenced by time of day, season, and geographic location. This intermittent nature of wind can lead to fluctuations in energy generation, posing challenges for grid stability.
  • Environmental and Wildlife Impact: Wind turbines can threaten local wildlife, especially birds and bats. Noise pollution and visual impact can also lead to concerns about landscape preservation and local opposition to wind farm installations.
  • Capital Costs: The initial installation costs of wind farms can be high, which can deter investment, particularly in developing economies. While operational costs are low, the up-front capital expenditure remains a challenge.
  • Public Acceptance and Policy Challenges: Despite the environmental benefits of wind power, public acceptance isn’t universal. Concerns about noise, aesthetics, and potential impacts on property values can lead to opposition. In addition, changing policies and regulatory uncertainty can pose significant hurdles.

Addressing these challenges requires a holistic approach, where technological advancements, policy interventions, and public engagement are all given their due importance. It’s through surmounting these hurdles that the full potential of wind energy can be realized, contributing to our global goal of a sustainable, low-carbon future.

The Government’s Role in the Development, Conservation, and Preservation of Wind Energy

Government at all levels plays a crucial role in developing, conserving, and preserving wind energy. This role is typically played out in several key areas:

  • Policy Formulation: Governments are responsible for establishing a supportive policy environment for wind energy development. This includes setting renewable energy targets, streamlining permit processes, and establishing regulations for wind farms’ safe and sustainable operation. They also can create incentives for wind energy development, such as tax credits or feed-in tariffs that provide a guaranteed price for wind energy producers.
  • Research and Development Support: Government agencies often fund or conduct research and development to advance wind energy technologies. This can range from supporting research into more efficient turbine designs to funding studies on the environmental impacts of wind farms. The results of this research can then inform policy and regulation.
  • Infrastructure Development: Governments play a crucial role in facilitating the development of the necessary infrastructure for wind energy. This could involve upgrading the electrical grid to accommodate wind energy better or investing in the development of offshore wind resources. Governments also often play a role in resolving land use issues, for example, by designating areas for wind energy development.
  • Education and Training: Governments can promote education and training programs to develop the skilled workforce needed for the wind energy sector. This can involve incorporating renewable energy topics into school curricula, supporting vocational training programs, or funding university research programs.
  • Public Engagement: Governments are often involved in public engagement around wind energy. This can include educating the public about the benefits of wind energy, addressing concerns about potential impacts, and exciting communities in decision-making processes about wind energy development.
